Image of Omron's G9KA-E High Power PCB Relay The Omron G9KA-E SPST-NO relay supports high-current applications with high-capacity load ratings. The high capacity and low contact resistance characteristics make the G9KA ideal for PV inverters/power conditioners, industrial inverters, and UPS systems. This 300 A high-power relay reduces the need for complex temperature designs and inclusion of heat transfer devices due to low contact resistance compared to similar relays. It can support designs with high voltage requirements of up to 1,000 V_AC.

Features and Benefits

1,000 V_AC; 50 A make, 300 A carry current, 50 A break at +85°C (30,000 ops N.O.)

Capable of supporting high-capacity switching and carrying currents

Low initial contact resistance: 0.2 mΩ max

Reduces heat generation due to contact resistance
Lower heat generation results in a lesser need for materials such as heat sinks

Holding voltage required is 45% to 60% of rated voltage

Reduces power consumption to 1 W from 5 W when held at 45% of rated V

Auxiliary contact Type 1B is also offered for contact weld detection requirements

Applications

Power conditioner inverters (PVI)
Industrial inverters
Uninterruptible power supplies (UPS)

High-voltage designs
EV charging stations

Precautions for G9KA Use

Do not connect to individual relays by probes or sockets; abnormal heat may be experienced by insufficient connections
Install and use relays with the recommended soldering conditions; avoiding recommendations may lead to abnormal heat generation
Do not use dropped relays, as the shock may cause improper relay operation
