General Purpose Relay
G7J
• Ideal for 3-phase motor control applications and resistive
and inductive loads.
• No contact chattering for momentary voltage drops up to
50% of rated voltage.
• Withstands more than 4 kV between contacts that are of
different polarity and between the coil and contacts.
• Flame-resistant materials (UL94V-0) used for all insulation.
• Push-to-test button on all models lets user check contact
operation.
• Class B coil insulation available.

Precautions
Note: Be sure to read the precautions and information common to all relays, contained in the Technical User’s Guide,
“Electromechanical Relays - Technical Information”, for correct use.
Allow suitable slack on leads when wiring, and do not subject the ter-
minals to excessive force.
■ Correct Use
Installation
Tightening torque: 0.98 N·m
PCB Terminal-equipped Relays weigh approximately 140 g. Be sure that
the PCB is strong enough to support them. We recommend dual-side
through-hole PCBs to reduce solder cracking from heat stress.
Do not impose excessive external force on the G7J in the horizontal
or vertical directions when inserting the G7J to the Faston receptacle
or pulling the G7J out from the Faston receptacle. Do not attempt to
insert or pull out more than one G7J Unit together.
Mount the G7J with its test button facing downwards. The Relay may
malfunction due to shock if the test button faces upwards. Be careful
not to press the test button by mistake because the contacts will go
ON if the test button is pressed.
Do not solder the tab terminals.
Operating Coil
Internal Connections of Coils
Be sure to use the test button for test purposes only.
The test button is used for Relay circuit tests, such as a circuit conti-
nuity test. Do not attempt to switch the load with the test button. If a
voltage is applied to the coil, the test button will retract in an ON state
(i.e., an excited state).

Micro Loads
AC coil
The G7J is used for switching power loads, such as motor, trans-
former, solenoid, lamp, and heater loads. Do not use the G7J for
switching minute loads, such as signals. Use a Relay with a bifur-
cated contact construction for switching micro loads, in which case,
however, only SPST-NO or SPST-NC output is obtained.
If a transistor drives the G7J, check the leakage current, and connect
a bleeder resistor if necessary.
Soldering PCB Terminals
Be sure to solder the PCB terminals manually only. In the case of
automatic soldering, some flux may stick to the test button and the
G7J. As a result, the G7J may malfunction.
The AC coil is provided with a built-in full-wave rectifier that prevens
contact chatter during a voltage drop. This circuit allows the relays to
withstand, with no vibration or shock, voltage drops to the coil of up
to 50% of the rated coil voltage for 1 second max.
The G7J is not of enclosed construction. Therefore, do not wash the
G7J with water or any detergent.
If a triac, such as an SSR, drives the AC coil of the G7J, the G7J may
not release. Be sure to perform a trial operation with the G7J and the
triac before applying them to actual use.
Connecting
Refer to the following diagram when connecting a wire with a screw
terminal to the G7J.
