Power relay offers lower contact resistance than comparable products

With the G9KC, Rutronik is adding another product from OMRON's power relay portfolio to its range. The four-pole component has a capacity of 480VAC at 40A and a low initial contact resistance of a maximum of 6mOhm. They can optionally be equipped with a Form B auxiliary contact, which provides reliable fault detection. The power relay outperforms comparable products with its extremely low contact resistance and impresses with its high short-circuit resistance in accordance with IEC62955. The components are, therefore, particularly suitable for use in three-phase EV charging stations, particularly for the European market.

The PCB relay has four poles, a contact resistance, and an optional auxiliary contact for reliable fault detection in accordance with the IEC60947-4-1 mirror contact requirement. Its failure rate (level M – reference value) is 100mA at 24VDC for the main contact and 10mA at 5VDC for the auxiliary contact. The relays also score points with their high short-circuit resistance in accordance with IEC62955.

The components operate reliably at an ambient temperature of -40C to +85C (without icing or condensation). Their compact dimensions are 35mm (width) x 58mm (length) x 47mm (height) with a contact gap of 3.6mm (minimum).

They are particularly suitable for use in three-phase EVSE mode 3 (EV charging stations) and are applicable to the currently highest models with 22kW (32A, three-phase 400VAC) - particularly for the EU market.

Typical pplication examples include three-phase EVSE mode 3, inverters for solar and energy storage and UPS.
