The DCNLB200NB48 is a normally closed, single-coil, side-mount contactor relay rated for 200A continuous current and 60V DC maximum voltage. It operates with a 48V DC coil and is designed for high-current switching applications such as communication power supplies and UPS systems. The relay has a mechanical life of 100,000 operations and an electrical life of 3,000 cycles at 48V DC. It supports a maximum short circuit current of 800A at 48V DC, maintains a maximum contact voltage drop of ≤50mV at 100A, and withstands 1000V AC dielectric voltage. Its operating temperature range is -40°C to +85°C, with ingress protection rated at IP40. The unit weighs 535g and features non-polarized contacts. The coil pickup voltage is 30V DC, dropout voltage is 4V DC, and coil power consumption is 12W at 25°C ambient temperature. Torque specifications for mounting are 9 to 11 N·m using M8 bolts.
