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 differ-
ent in polarity and between the coil and contacts.
• Flame-resistant materials (UL94V-0-qualifying) used for all in-
sulation material.
• Standard models approved by UL and CSA.
