Power Relay, G7J (Part Numbers)

Power Relay, G7J

OMRON

OMRON

[Features]
· Multipolar power relay that brings us a step closer to a high capacity, high voltage contactor area.
· Strong power, not only for induction load, but also for motor control.
· No contact chattering even in the event that there is an instantaneous power drop of 50% of the rated voltage.
· Resistance voltage of 4kV or more not only between the coil and contacts, but also between the non-polar contacts.
· All insulating materials are flame retardant and have passed UL94V-0 standards.
· UL, CSA standard certification for standard models.
· Contact gap of 3 mm or more (both sides).

G7J external appearance

  • Its high capacity allows it to be used for not just resistive and inductive loads but also for motor controls.
  • No contact chattering for momentary voltage drops up to 50% of the rated voltage.
  • Withstanding more than 4 KV between contacts of different poles as well as between the coil and contacts.
