The DCNHR300QFA is a 900V DC normally open contactor relay with polarized main contacts and an auxiliary contact, designed for continuous current ratings up to 500A using 400MCM cable. It features a resin housing for corrosion resistance, sealed contacts to prevent electrical arc leakage, and a PWM coil for reduced holding power consumption. Operating temperature ranges from -40°C to +85°C. The relay meets UL File Number E47258 recognition and CE standard EN 60947-4-1, 2018. It is mounted on the bottom with a 9~36V DC coil and is RoHS compliant.
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 (DCNHR300QFA) is for 300A contact switching. It includes an auxiliary contact and features polarized main contacts. Designed for 300 A contact switching Polarized main contacts Includes an auxiliary contact
