actual load.
*2. The electrical load performance value for the 10A, 20A, 80A, 120A and 200A types applies when a varistor is connected in parallel to the coil. Please be warned
that working life will be reduced when a diode is used.
*3. Condition: Nominal switching 10 cycles, each cut-off 2,500 A
*4. The coil voltage 12 V DC type and 24 V DC type have the same specifications.

NOTES
1. Usage, transport and storage conditions
1) Temperature: –40 to +80°C –40 to +176°F
2) Humidity: 5 to 85% RH (Avoid freezing and condensation.)
The humidity range varies with the temperature. Use within the
range indicated in the graph below.
4. Electrical life
This relay is a high-voltage direct-current switch. In its final
breakdown mode, it may lose the ability to provide the proper
cut-off. Therefore, do not exceed the indicated switching
capacity and life. (Please treat the relay as a product with limited
life and replace it when necessary.)
In the event that the relay loses cut-off ability, there is a
possibility that burning may spread to surrounding parts, so
configure the layout so that the power is turned off within one
second.
3) Atmospheric pressure: 86 to 106 kPa

5. Permeation life of internal gas
This relay uses a hermetically encased contact (capsule
contact) with gas inside. The gas has a permeation life that is
affected by the temperature inside the capsule contact (ambient
temperature + temperature rise due to flow of electrical current).
For this reason, make sure the ambient operating temperature is
between –40 and 80°C –40 and +176°F (200A and 300A types:
Max. 85°C 185°F), and the ambient storage temperature is
between –40 and 85°C –40 and +185°F.

4) Condensation
Condensation forms when there is a sudden change in
temperature under high temperature and high humidity
conditions. Condensation will cause deterioration of the relay
insulation.
6.The coils (300 A type) and contacts (all type) of the relay
are polarized, so follow the connection schematic when
connecting the coils and contacts.
5) Low temperature, low humidity environments
The plastic becomes brittle if the relay is exposed to a low
temperature, low humidity environment for long periods of time.
Type 300 A contains a reverse surge voltage absorption circuit;
therefore a surge protector is not needed.
7. For the 300 A type, drive the coil with a quick startup.
2. When installing the relay, always use washers to prevent
the screws from loosening.
(Built-in one-shot pulse generator circuit)
• Regarding the torque value for contact terminal, it is intended
that secure an electrical connection stability by getting enough
contact pressure (Axial force) of fixing part.
Therefore, please do not use the screw (a bolt and a nut)
preventing looseness needing running torque (Prevailing torque
type and Self lock type) because enough tightening force in axial
direction may not be secured.
In addition, there is high possibility that a case of a relay may be
broken if users use the nut for EV80A and EV120A.
Because excessive torque is applied to a case of a relay before
generation of contact pressure. (Axial force).
• Regarding the torque value for the main body of a relay, please
use suitable screw on own verification.
8. After the ON signal enters the 300A type, automatic coil
current switching occurs after approximately 0.1 seconds.
Do not repeatedly turn it OFF within that 0.1 seconds
interval, as doing so may damage the relay.
9. Be careful that foreign matter and oils and fats kind don’t
stick to the main terminal parts because it is likely to cause
terminal parts to give off unusual heat.
Also, please use the following materials for connected
harnesses and bus bars.
10A type: Min. 2 mm2 nominal cross-sectional area
20A type: Min. 3 mm2 nominal cross-sectional area
80A type: Min. 15 mm2 nominal cross-sectional area
120A type: Min. 38 mm2 nominal cross-sectional area
200A type: Min. 60 mm2 nominal cross-sectional area
300A type: Min. 100 mm2 nominal cross-sectional area
3. Condition of tightening screw
Tighten each screw within the rated range given below.
Exceeding the maximum torque may result in breakage.
Mounting is possible in either direction.
<Relay attaching portion>
• M4 screw (for 10A type): 1.8 to 2.7 N·m
• M5 screw (for 20A, 80A, 120A, 200A and 300A types): 3 to 4
N·m
10. As a guide, the insertion strength of the plug-in terminal
into the relay tab terminal should be 40 to 70N (10A type), 40
to 80N (20A type). Please select a plug-in terminal (flat
connection terminal) which comply with JIS C2809-1999.
10A type: for plate thickness 0.5mm and #187 tab terminal
20A type: for plate thickness 0.8mm and #250 tab terminal
<Main terminal attaching portion>
• M5 (for 80A type): 3 to 4 N·m
• M6 (for 120A and 200A types): 6 to 8 N·m
• M8 (for 300A type): 10 to 12 N·m
11. Avoid excessive load applied to the terminal in case of
installing such as a bus bar etc., Because it might adversely
affect the opening and closing performance.
12. Use the specified connector for the connector terminal
connection (80A, 120A and 300A)

13. Cautions for use
12) The relay contacts are encapsulated in an inert gas
atmosphere. Care must be exercised when the relay is to be
used or stored at high ambient temperature.
13) If the power is turned off and then immediately on after
applying the rated voltage (current) continuously to the relay’s
coil and contact, the resistance of the coil will increase due to a
rise in the coil temperature.
1) Regarding cautions for use and explanation of technical
terms, please refer to our “Automotive Relays Automation
Controls Group Catalog”.
2) Additionally the ambient temperature and condition for your
application should be considered because pick-up and drop-out
voltage will be changed.
3) If it includes ripple, the ripple factor should be less than 5%.
For coil surge absorption, please use a zener diode or varistor,
etc., so that the clamp voltage reaches 1.5 times or more (at
least 18 V for rated 12 V type) the rated operation voltage.
If only a diode is connected in parallel with the relay coil, the
contact opening velocity will become slow and sufficient cutoff
performance cannot be guaranteed. Please avoid such usage.
Ex. 1: When using a varistor
This causes the pick-up voltage to rise, and possibly exceed the
rated pick-up voltage. In these circumstances, take measures
such as reducing the load current, limiting the duration of current
flow, and applying a coil voltage higher than the rated operating
voltage (quick start).
14) In case using a capacitive load (C-load), please take a
countermeasure as pre-charging to the capacitive load so that
the inrush current will not surpass 60A.
Recommended Varistor; Maximum Energy: more than 1J
(However, please make settings using values that take into
consideration the worst case scenario.)
The relay might have a contact welding without such
countermeasure.
15) If the relay is used for an inductive load (L load) such that
L/R > 1ms, add surge protection in parallel with the inductive
load. If this is not done, the electrical life will decrease and cut-
off failure may occur.
16) Use the suitable wire for wire at the load side according to
the current. If the wire diameter is small, the maximum rated
contact current cannot be guaranteed.
(Ex.) Carrying current; 60A: diameter of 15mm2 or more
17) Take care to disconnect to the power supply when wiring.
18) Do not switch the contacts without any load as the contact
resistance may become increased rapidly.
Varistor voltage: For 12 V DC input, Min. 18 V

of organic solvent (as benzene, thinner and alcohol) and the
strong alkali (as ammonia and caustic soda) might be adhered
to this product.

21) Be careful that foreign matter and oils and fats kind don’t
stick to the main terminal parts because it is likely to cause
terminal parts to give off unusual heat.
22) Do not make additional manufacturing upon the relay
housing.
4) Lifetime is specified under the standard test conditions in JIS
C 5442. (temperature 15 to 35°C 59 to 95°F, humidity 25%RH to
85%RH)
Lifetime is dependent on the coil driving circuit, load type,
operation frequency and ambient conditions. Check lifetime
under the actual condition.
23) For AC shutoff these is no contact polarity, but confirm the
electric life using the actual load.
Especially, Contact terminals have polarity. So if the contact
terminals were connected with opposite pole, the electric life
would be shorter.
5) When applying current which includes precipitous changes or
ripple, the relay may generate buzzing sound. Therefore, please
confirm with the actual load.
6) If the relay is used while exceeding the coil rating, contact
rating or cycle lifetime, this may result in the risk of overheating.
7) As a general rule, do not use a relay if it has been dropped.
8) Take care to avoid cross connections as they may cause
malfunctions or overheating.
9) When the screws for fixing relay-body and for additional
terminal are tightened, it should be used within the range of
decided torque.
10) Avoid mounting the relay in strong magnetic fields (near a
transformer or magnet) or close to an object that radiates heat.
11) If the several relays are mounted closely or a heat-
generation object is close to the relay, take care to check the
abnormal temperature-rise and the insulation distance between
the terminals outside of the relay.
For general cautions for use, please refer to the “CAUTIONS FOR USE OF AUTOMOTIVE RELAYS”
