EP RELAYS;
PANASONIC 
(10A, 20A and 80A types)
200A type has been added.
High Capacity of Max.
1,000 V DC Cut-off Possible
EP RELAYS (AEP)
FEATURES
1. High-voltage, high-current control
capable
6. Mounting direction is not specified
The weight of the movable parts is light,
and also the restoring force is large,
hence the relay is relatively unaffected by
gravity.
7. Wide selection of models available.
Types include PC board type (10A),
TM type (10A and 20A), Lead wire type
(200A) and Connector type (80A and
300A).
400V DC high-voltage switching and
1,000V DC cut-off has been achieved
thanks to a sealed construction with
mixed hydrogen gas and the magnetic
arc motion through use of a permanent
magnet.
2. Compact & Low Operating Sound
By using a capsule contact mechanism
that is enclosed with hydrogen gas, high-
capacity cutoff is possible even with a tiny
contact gap. There is little operating
sound, which does not change even
when large currents are cut off.
3. Arc space unnecessary
The enclosure box can be made smaller
thanks to an arc-space-free construction
from which the arc will not get out.
4. Safety
Since the contacts are enclosed in a
sealed capsule structure, the arc will not
get out, which ensures safety.

NOTES
1. Please read “GENERAL
3.The contacts of the relay are
polarized. Please follow instructions
in the connection schematic when
connecting the contacts.
We recommend installing a surge
protector varistor for the 10A, 20A, 80A
and 200A types. Please note that when
using a diode, the switching speed may
decrease and cause a reduction in cut-off
performance. For the 300A type,
separate surge countermeasures are not
required, because it contains a built-in
surge absorbing element.
6. Electrical life
APPLICATION GUIDELINES” for
regular cautionary items.
2. When installing the relay, always
use washers to prevent the screws
from loosening.
Tighten each screw within the rated
range given below. Exceeding the
maximum torque may result in breakage.
Mounting is possible in either direction.
• M5 screw (20A, 80A, 200A and 300A
main unit mounting section): 3 to 4N·m
• M4 screw (10A PC board type main unit
mounting section): 0.98 to 1.2N·m
(10A TM type main unit mounting
section): 1.8 to 2.7N·m
This relay is a DC high-voltage 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 and from the
point of view of safety, consider installing
a failsafe circuit in the device.
<Recommend varistor>
Amount of proof energy: Min. 1 J
Varistor voltage: 1.5 to 3.0 times of
nominal voltage
4. Do not use a relay if it has been
dropped.
Also, in order to avoid increased contact
resistance, do not operate when there is
no switching load.
Recommended securing torque on load
side terminals
• 80A/M5 bolt: 3.5 to 6.5 N·m
• 200A/M6 bolt: 6 to 8 N·m
• 300A/M8 bolt: 10 to 12 N·m
5. Avoid mounting the relay in strong
magnetic fields (near a transformer or
magnet) or close to an object that
radiates heat.

7. 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).Therefore, please do not exceed
the operation ambient and storage
ambient temperatures given in the
specifications.
8. Do not disassemble the relay.
Please note that disassembling the
relay will invalidate the warranty.
9. 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.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
14. Main contact ratings in the ratings
apply to when there is a resistive load.
If you are using an inductive load (L
load) such that L/R > 1 ms, 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.
In order to prevent contact welding
when using a capacitive load (C load)
such as a capacitor load, please make
the inrush current setting more than
two times that of the nominal current.
Please contact us for more
17. Place the PC board mount type
(10A PC board type) securely by hand
soldering after attaching it using M4
screw. Don’t submerge assembled
board in cleaning solvent or water.
Also, be careful not let flux overflow
up from the PC board or adhere to the
base of the relay.
Recommended hand soldering
conditions
• Soldering iron: 30 to 60 W
• Tip temperature: 400°C 752°F
• Solder time: within approx. 5 seconds
18. Make sure the power is turned off
when wiring.
19. Incorrect wiring may cause
unexpected malfunction and failure.
20. Regarding AC cutoff, although
there is no contact polarity, generally
it is thought that the electrical life will
shorten due to cutoff in the reverse
direction, compared to DC cutoff.
Confirm electrical life using actual
load. In the case of DC cut-off, please
note the contact polarity.
information.
15. 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 TM type:
#187, 0.5 mm board thickness
20A TM type:
#250, 0.8 mm board thickness

copper) is used as pre-solder for the
terminals of the PC board mount type

tab terminal (JIS C289-1999 compliant,
flat type connection terminal)
operating voltage.
10. Pure DC current should be applied
to the coil. If it includes ripple, the
ripple factor should be less than 5%.
However, check the actual circuit
since the characteristics may be
slightly different.The power supply
waveform supplied to the coil should
be rectangular. Also, the 300A type
has a built-in dedicated drive circuit. It
may not operate normally unless the
rise time is 10 ms or less.
11. Don’t exceed maximum coil
voltage. Exceeding maximum
allowable coil voltage on continuous
basis will damage the relay and could
case failure.
12. If you will be using with a load
voltage that exceeds 400 V DC, please
be sure to verify operation on the
actual device, referring to the
switching life curves (reference data).
You must absolutely avoid continual
use in which the load current exceeds
the rated value.This will cause
abnormal heating.

Load input terminal side;
22.The warranted tensile strength of
the female connector lead wire used
for connection that comes with the
80A and 300A connector type when
attaching it to the relay body is 98N.
Avoid excessive tension as this is a
cause of broken wires and damage.
Also, insert the female connector
deeply and make sure the connection
is secure.
23. Condensation will occur during
sudden temperature changes in hot
and humid environments. Caution is
required, because condensation will
cause a decrease in the insulation
resistance between the terminals.
10A TM type: min. 2.0 mm2
20A TM type: min. 3.0 mm2
Coil input terminal side;
10A and 20A TM types: min. 0.3 mm2
80A type: min. 15 mm2
200A type: min. 60 mm2
300A type: min. 100 mm2
16. Use 40 to 70N or 50 to 80N of force
as a guide to fasten the terminal
connected to the 10A TM and 20A TM
types. Please use caution when
inserting or removing the terminal as
the relay tab terminal may cause
injuly. Also, unstable conductivity and
abnormal terminal heating may occur;
therefore, please check that there is
no deformation of or foreign objects
on the faston terminals (blade
receptacle) you will be connecting.
Use JIS C2809 (or IEC60760) certified
products.
13.The rated control capacity and life
are given as general guides.
It is important to conduct sufficient tests
on the actual device, because contact
properties and working life will differ
considerably depending on the type of
load and conditions.
