DCNH Electromechanical Contactor Relays

Littelfuse DCNH Electromechanical Contactor Relays feature high-voltage DC switching capabilities to control and interrupt high-power DC circuits safely. These relays are housed in a robust, sealed construction built for reliability in harsh environments with protection against dust, moisture, and arc leakage. The DCNH contactor relays include bidirectional and non-polarized operation, which supports flexible system integration across a wide range of applications. These relays provide simplified installations and secure connections in a compact integrated design for a space-saving form factor. Typical applications include battery energy systems, storage devices, electric vehicles, electrified mobility platforms, industrial power distribution, control systems, charging infrastructure, and high-power DC switching.
