The DCNHR40PF24 is a normally open, single-pole, single-throw DC contactor relay with a 24V coil, rated for 40A continuous current and 900V DC maximum voltage. It features a resin housing for corrosion resistance, sealed contacts to prevent electrical arc leakage, and a non-polarized contact configuration. The relay operates within a temperature range of -40°C to +85°C and meets UL E47258 recognition and CE EN 60947-4-1:2018 standards. It uses a bottom-mounting style with M5 bolt terminals requiring 1.7-2.0 N·m torque for main connections and M4 terminals for coil connections requiring 1.8-2.3 N·m torque. The product is RoHS compliant and incorporates a non-PWM coil design.
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 (DCNHR40PF24) is for 40A contact switching and features polarized main contacts and a 24V coil.
