G7J

A High-capacity, High-dielectric-strength,
Multi-pole Relay Used Like a Contactor

• Miniature hinge for maximum switching power for motor loads
as well as resistive and inductive loads.

• No contact chattering for momentary voltage drops up to 50%
of rated voltage.

• Withstanding more than 4 kV between contacts that are differ­ent in polarity and between the coil and contacts.

• Flame-resistant materials (UL94V-0-qualifying) used for all in­sulation material.

• Standard models approved by UL and CSA.

Specifications

■ Coil Ratings

Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/–20% for AC rated current and

±15% for DC coil resistance. (The values given for AC rated current apply at 50 Hz or 60 Hz.)

2. Performance characteristic data are measured at a coil temperature of 23°C.

3. The maximum voltage is one that is applicable to the Relay coil at 23°C.

■ Contact Ratings

Note: The values in parentheses indicate values for a bifurcated contact.
