The DCNHR50QF12 is a normally open, single-pole, single-throw DC contactor relay with a 12V nominal coil voltage, designed for 50A continuous current and rated up to 900V DC. It features polarized main contacts and a mechanically linked normally open auxiliary contact, with a resin housing for corrosion resistance in harsh automotive environments. The relay includes a pulse width modulation (PWM) coil to reduce holding power consumption, sealed contacts to prevent electrical arc leakage, and is rated for operation between -40°C and +85°C. It meets UL E47258 recognition and CE EN 60947-4-1, 2018 standards. The main contacts are IP67 rated, the PWM circuit is IP54, and it uses a 10AWG cable. The mounting style is bottom mount with a 450V DC system voltage.
The DCNHR Series 900V Max 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 (DCNHR50QF12) is for 50A contact switching. It includes an auxiliary contact and features polarized main contacts and a 12V coil. Designed for 50 A contact switching Polarized main contacts Includes an auxiliary contact 12 V coil rating
