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.

Note:
The G7J relays require a W-bracket for mounting. Order the bracket separately below. To order a relay and bracket packed together,
add “-W1” to the part number before the coil voltage suffix. For example, G7J-2A2B-B-W1-AC100/120.
Model Number Legend
To Order: Select the part number and add the desired coil voltage rating (e.g., G7J-3A1B-B-AC100/120).
