The DCNHR300PFA is a 900V DC normally open contactor relay with a resin housing for corrosion resistance in harsh automotive environments. It supports continuous current up to 500A using 400MCM cable and features a pulse width modulation (PWM) coil to reduce holding power consumption. Main contacts are sealed to prevent electrical arc leakage and provide IP67 ingress protection. The relay has a single normally open auxiliary contact, operates within -40°C to +85°C, and is rated for 2000A at 320V DC transient conditions. It meets UL E47258 recognition and CE EN 60947-4-1:2018 standards. Mounting is bottom-mounted with M8 bolts requiring 8 to 12 N·m torque.
The DCNHR Series 450V High-Voltage DC Contactor Relay is normally open with a low-power coil in a corrosion-resistant housing for use in harsh vehicle environments. The contactor's permanent magnet helps to achieve a high-voltage DC cutoff.This DCNHR Series contactor relay (DCNHR300PFA) is for 300A contact switching and features polarized main contacts. Designed for 300A contact switching Polarized main contacts
