Image of Omron Electronics Inc-EMC Div's G9KC-4A AC Multi-Pole PCB Relay Omron's G9KC-4A 4PST-NO relay supports multiple line disconnects in one package at voltages up to 480 V_AC. The G9KC’s multiple-pole feature is aimed towards 3-phase AC designs. The high capacity and low contact resistance characteristics make the G9KC ideal for 3-phase EV charging stations, PV inverters/power conditioners, and UPS systems. The low 6 mΩ maximum contact resistance reduces the necessity for complex temperature designs and inclusion of heat transfer devices due to low contact resistance when compared to similar relays. Auxiliary contact models are also available for an SPST-NC mirror contact, allowing reliable failure detection.

Features

4-pole switching

40 A at 480 V_AC (30,000 ops.)
32 A at 277 V_AC (50,000 ops.)

Low max. contact resistance (6 mΩ max)
Auxiliary contact models available (G9KC-4A1B models)

Applications

EV charging stations
Power conditioner inverters (PVI)
Industrial inverters
Uninterruptable power supplies (UPS)

Benefits

Capable of supporting two common AC voltage levels with multi-pole switching
Ideal for 3-phase applications
Reduces heat generation due to contact resistance
Lower heat generation results in a lesser need for materials such as heatsinks
Mirrors the position of main contacts, providing reliable failure detection
