Omron Electronics G9KC AC Multi-Pole PCB Power Relays

Omron Electronics G9KC AC Multi-Pole PCB Power Relays are 4PST-NO relays that support multiple line disconnects in one package at voltages up to 480VAC. The multiple pole feature is designed for three-phase AC designs, and the high capacity and low contact resistance characteristics are ideal for electric vehicle (EV) charging stations (3-phase), uninterruptible power supply (UPS) systems, and photovoltaic (PV) inverters/power conditioners. These relays offer a low maximum contact resistance of 6mΩ, which minimizes the need for both complex temperature designs and the inclusion of heat transfer devices. The G9KC series includes auxiliary contact models for an SPST-NC mirror contact, allowing reliable failure detection. Omron Electronics G9KC AC Multi-Pole PCB Power Relays are available in a compact size of 35mm x 58mm x 47mm with a 3.6mm minimum contact gap.

Features

  • 4-pole switching at 40A at 480VAC (30,000 operations) and 32A at 277VAC (50,000 operations)
    • Supports 2 common AC voltage levels with multi-pole switching
    • Ideal for 3-phase applications
  • Low 6mΩ maximum contact resistance
    • Reduces heat generation due to contact resistance
    • Lower heat generation reduces need for heat sinks and other materials
  • Compact size of 35mm x 58mm x 47mm
  • 3.6mm minimum contact gap
  • High short-circuit capacity compliant with IEC 62955
  • Low coil power consumption of approximately 613mW with holding voltage at 35%
  • Auxiliary contact models available (G9KC-4A1B), mirrors position of main contacts to provide reliable failure detection

Applications

  • EV charging stations
  • Inverters for solar and energy storage
  • UPS
