The DCNHF300 Series high-voltage DC contactor relay is engineered for demanding electric vehicle and industrial high-power DC applications that require robust, reliable switching at high current levels. Rated for 300A continuous current and up to 1000V DC, it is ideal for use in battery power supply systems, charging infrastructure, motor control, circuit isolation, circuit protection, and industrial safety systems.
Featuring SPST normally open (NO) circuitry with non-polarized contacts, the DCNHF300 Series contactor supports bidirectional current flow, providing flexibility across a wide range of electrical systems. Its bottom mounting design enables secure installation, while the rugged construction is optimized for performance in harsh automotive and industrial environments.
The DCNHF300 Series contactor is equipped with internal-thread terminals to ensure secure high-current connections. It is available with 12V DC or 24V DC coil voltage options, supporting common EV and industrial control system requirements.
This model (DCNHF300NG24-F) features a 24V DC coil rating.
