The DCNHE300 Series high-voltage DC contactor relay is designed for electric vehicle and industrial applications, including battery power supply, charging systems, motor control, circuit isolation, and circuit protection. Its compact, corrosion-resistant resin housing ensures reliable performance in harsh environments. Sealed contacts prevent contamination and electrical arc leakage, providing maximum safety and long-term reliability.
Supporting 300A continuous current—or up to 500A when using 400 MCM cable—the SPST normally open (NO) contact circuitry handles a maximum voltage of 1000V DC. A PWM coil design reduces power consumption and heat generation during operation. The DCNHE300 Series contactor is offered with non-polarized load terminals in internal-thread or stud terminal configurations, along with a 12–36V DC coil voltage rating, delivering flexible, high-performance DC switching for demanding applications.
