The DCNLM200NB48 is a 60V DC maximum normally open SPST contactor relay with a 200A continuous current rating and a 48V coil voltage, mounted on the side. It features non-polarized main contacts and a dual-coil configuration, with a dielectric withstand voltage of 1000V AC, an insulation resistance of ≥50MΩ at 500V DC, and a contact voltage drop of ≤50mV at 100A. The relay operates from -40°C to +70°C, has an electrical life of 6000 cycles at 48V DC, and a mechanical life of 100,000 cycles. Terminal torque is 9-11N·m for contact terminals and 1.7-2.5N·m for coil terminals using M4 bolts. Weight is 445.1g.
The DCNLM Series 48V High-Current DC Contactor Relay features 200A contact switching capability with a 48V coil rating, which is suitable for a wide variety of applications, including use in electrical control systems, communication power supplies, engineering machines, and uninterruptible power supplies (UPS).This configuration of the DCNLM normally open, high-current DC contactor (DCNLM200NB48) features 48V non-polarized main contacts and a dual-coil design that reduces drain on the electrical system. 200 A continuous current rating for high-current contact switching 800 A 5 ms make–break rating 48 V coil rating Dual-coil relay design reduces electrical system drain
