EHW800 800A 12V RW800 Busbar DC Contactor
EHW800 is a high-capacity Busbar DC Contactor designed for low-voltage, high-current applications in energy storage and DC power systems. With a rated contact current of 800A and a switching voltage of up to 80VDC, it is optimized for busbar-based direct current systems requiring stable and efficient contact control.
The device features a single-pole, normally open (SPST-NO) contact arrangement and supports multiple coil voltage options, including 12V, 24V, 48V, and 72VDC.
Optional features such as magnetic latching and a micro switch auxiliary contact allow for enhanced energy efficiency and status feedback in custom-built systems.
