The DCNHR150QFA is a normally open, 900V DC max contactor relay with a resin housing for corrosion resistance in harsh automotive environments. It supports 150A continuous current with 2AWG cable and features a PWM coil for reduced holding power, polarized main contacts, and a normally open auxiliary contact. The relay is rated for operating temperatures from -40°C to +85°C, has an IP67 rating for main contacts, and meets UL E47258 and EN 60947-4-1, 2018 standards. It employs a permanent magnet arc extinguishing system and is RoHS compliant.
The DCNHR Series 900V Max High-Current High-Voltage DC Contactor Relay is a normally open (also known as monostable) PWM relay with a resin body for corrosion resistance in harsh automotive environments. Sealed contacts help ensure there is no leakage of electrical arc for safety. The high-current relay's permanent magnet blows the magnetic field horizontally to achieve a high-voltage DC cutoff.This DCNHR Series contactor relay (DCNHR150QFA) is for 150A contact switching. It includes an auxiliary contact and features polarized main contacts. Designed for 150 A contact switching Polarized main contacts Includes an auxiliary contact
