The DCNLM200NB12 is a 60V DC maximum, normally open, single-coil contactor relay with a 200A continuous current rating, designed for stationary applications such as communication power supplies and uninterruptible power supplies (UPS). It features 48V non-polarized main contacts, side mounting, and a 12V DC coil rating. The device has a dielectric strength of 1000V AC, an insulation resistance of at least 50MΩ at 500V DC, and operates within a temperature range of -40°C to +70°C. It supports a maximum short-circuit current of 800A at 48V DC and has a mechanical life of 100,000 cycles. The main contact voltage drop is ≤50mV at 100A. The part is shipped with side mounting and uses a bolted connection with M8 terminals requiring 9-11 N·m torque for secure installation.
The DCNLM Series 48V High-Current DC Contactor Relay features 200A contact switching capability with a 12V 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 (DCNLM200NB12) features 48V non-polarized main contacts and a dual-coil design that reduces drain on the electrical system. 200A continuous current rating for high-current contact switching 800A 5 ms make-break rating 12V coil rating Dual-coil relay design reduces electrical system drain
