The DCNHF800NH Series high-voltage DC contactor relay is engineered for demanding electric vehicle and industrial high-power DC applications that require high current capacity and reliable high-voltage switching. Rated for 800A continuous current and up to 1500V DC contact voltage, it is well suited for use in battery power supply systems, charging piles, motor control, circuit isolation, circuit protection, and safety devices for industrial machinery.
Featuring SPST normally open (NO) circuitry with non-polarized contacts, the DCNHF800NH Series contactor supports bidirectional current switching to accommodate a wide range of electrical systems. A double-coil design enhances operational stability in high-power applications, while the bottom-mounting configuration supports secure installation in EV and industrial systems.
The DCNHF800NH Series contactor is equipped with stud terminals for high-current load connections and wire leads for the control circuit, enabling flexible integration into control systems. It is available with 12V DC or 24V DC coil voltage options to support common EV and industrial control requirements.
This model (DCNHF800NH12-B) features a 12V DC coil rating.
