The DCNHR50QF24 is a 900V DC normally open contactor relay with a 24V coil, polarized main contacts, and a normally closed auxiliary contact, designed for 50A continuous current switching. It features a resin housing for corrosion resistance, sealed contacts to prevent arc leakage, and a PWM-compatible coil system for reduced holding power. The relay is rated for operation 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 mounts on a bottom surface with M5 bolt holes and requires 1.7-2.0 N·m torque for terminal connections. The part includes mechanically linked auxiliary contacts and is RoHS compliant.
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 (DCNHR50QF24) is for 50A contact switching. It includes an auxiliary contact and features polarized main contacts and a 24V coil. Designed for 50A contact switching Polarized main contacts Includes an auxiliary contact 24V coil rating
