The DCNHR200QFA is a 900V DC normally open contactor relay with a resin housing for corrosion resistance in harsh automotive environments. It supports 200A continuous current using 0AWG cable and features a PWM coil operating from 9 to 36V DC to reduce holding power. The relay includes mechanically linked normally open auxiliary contacts and polarized main contacts for polarity-sensitive applications. It meets UL E47258 recognition and CE EN 60947-4-1:2018 standards. Mounting is bottom, with a 1.8-3.5N.m torque specification for coil terminal connections. Operating temperature ranges from -40°C to +85°C, and main contacts are rated IP67. The auxiliary contacts have a maximum rating of 2A at 24V DC. The relay has a make time of 25ms and release time of 12ms.
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 (DCNHR200QFA) is for 200A contact switching. It includes an auxiliary contact and features polarized main contacts. Designed for 200 A contact switching Polarized main contacts Includes an auxiliary contact
