G6QE PCB Power Relay

The G6QE is a miniature PCB power relay with a high switching capacity of 36A and a 10kV impulse withstand voltage. This low height single-pole power relay also has a 12% reduced power consumption compared with rated coil consumption. It provides energy saving by allowing the holding voltage method, which also lowers heat generation in the application.

Key features & benefits
  • Switching capacity: 36A at 250VAC (10,000 operations); 30A at 250VAC (100,000 operations)
  • 10kV impulse withstand voltage
  • Conforms to cULus, EN and CQC
  • Miniature size
  • 12% reduced power consumption compared with rated coil consumption

G7J Power Relay

Utilized as a contactor, the OMRON G7J series are high-capacity, high-dielectric-strength, multi-pole power relays. They include a miniature hinge providing maximum switching power for motor loads, as well as resistive and inductive loads. Withstanding more than 4 kV between contacts that are different in polarity, and between the coil and contacts, they are also immune to contact chattering for momentary voltage drops of up to 50% of rated voltage. The G7J standard models are approved by UL and CSA.

Key features & benefits
  • High capacity, multi-pole relay
  • High dielectric strength
  • Miniature hinge for maximum switching power
  • No contact chattering for momentary voltage drops up to 50% of rated voltage
  • Flame resistant materials used

G7EB PCB Power Relay

The OMRON G7EB has a switching capacity up to 100A at 800VAC, as well as 100A at 60VDC. Its ultra-low 5mΩ contact resistance greatly reduces heat generation within the component and minimizes energy waste. As a result, the G7EB experiences a temperature rise to about +40ºC with a 100A carry current. This 40.5 x 50.5 x 37mm relay helps reduce overall system size, while its reduced requirement for heat sinks yields further space savings for the system designers.

Key features & benefits
  • Switching capacity: 100A at 800VAC; 100A at 60VDC
  • Low contact resistance (5mΩ)
  • Ambient temperature 85°C
  • 10kV impulse withstand voltage
  • Contact gap ≥3.6mm

G9KA PCB Power Relay

The OMRON G9KA is a compact and efficient 800VAC/200A high power relay aimed at power conditioners (PCS) associated with renewable micro-power generation, as well as EV chargers, inverters and UPS applications. It is an ideal relay solution for grid interconnection and safety interruption in applications demanding high energy efficiency and low heat generation. The G9KA benefits from an exceptionally low contact resistance for this class of relay of just 0.2mΩ, reducing the heat generated in the relay by over 30% compared with current equivalent devices. This facilitates the thermal design and reduces design cost.

Key features & benefits
  • 800VAC/200A breaking
  • Low initial contact resistance (0.2mΩ)
  • Ambient temperature up to 85°C
  • 10kV impulse withstand voltage
  • Contact gap ≥4.0mm
