Power Relay, G7J (OMRON)

Power Relay, G7J (OMRON)

[Features]
· A multipolar power relay that is one step closer to the contactor region and can deliver high capacity and high voltage.
· The resistance and induction loads are high capacity and able to withstand motor controls.
· Zero contact chattering, even during momentary drops in voltage, up to 50% of the rated voltage.
· The withstand voltage between the coil and contacts, as well as that between different pole contacts, clears 4 kV or higher.
· All of the insulating materials use flame retardant materials that comply with UL94V-0 standards.
· The standard product is a UL and CSA standard certified type.
· The contact gap is 3 mm or more (both sides).
