The SGX 750V, 150A contactors, featuring ceramic-to-metal weld technology, are now available for use in a wide range of applications—including residential energy storage systems (ESS), DC fast charging, electric forklifts, automated guided vehicles (AGVs), and other industrial vehicles.
Designed to offer a strong performance-to-cost ratio, the SGX150 750V/150A High Voltage DC Contactor serves as a reliable drop-in replacement for many competing brands, combining durability with value.
Each contactor is hermetically sealed and rated for temperatures up to 175 °C, significantly reducing the risk of fire or failure under overcurrent conditions.
The internal chamber is backfilled with a hydrogen-based gas mixture to prevent oxidation, ensuring low and stable contact resistance throughout the product’s lifespan.
