G9KD PCB High-Power 1,500 VDC Relays

Omron G9KD series relays are designed for high-voltage, high-current DC switching, supporting DC systems up to 1,500 V_DC, enabling reliable operation in demanding power applications. Its air-switching design without hydrogen gas improves overall safety while offering greater design flexibility compared to gas-filled alternatives. This relay has an auxiliary contact option with IEC mirror contact compliance that enhances safety and reliability within control circuits, making it well suited for critical system protection.

As EV chargers and energy storage systems (ESS) move toward higher capacity and output, demand is increasing for DC relays capable of breaking high current at 1,000 V_DC. In particular, EV fast chargers often require dozens of switching devices operating simultaneously, and customers focused on PCB integration and automation need solutions that support PCB mounting.
