The DCNHR50PF48 is a normally open, single-pole single-throw DC contactor relay rated for 900 V DC and 50 A continuous current, designed for automotive and industrial applications. It features a resin housing for corrosion resistance, sealed contacts to prevent electrical arc leakage, and a 48 V nominal coil voltage. The main contacts are rated IP67, and the PWM circuit is rated IP54. Operating temperature ranges from -40 °C to +85 °C. It has a bottom mounting style, uses 10 AWG cable, and complies with UL E47258 and EN 60947-4-1:2018. Auxiliary contacts are normally open and mechanically linked.
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 (DCNHR50PF48) is for 50A contact switching and features polarized main contacts and a 48V coil. Designed for 50A contact switching Polarized main contacts 48V coil rating
