The DCNLM400NB24-01 is a 400A continuous current, normally open, single-pole single-throw DC contactor rated for 60V DC maximum with a 24V DC coil. It features non-polarized main contacts and a dual-coil configuration. The device is side-mounted and designed for stationary applications such as uninterruptible power supplies and communication power systems. It has an operating temperature range of -40°C to +70°C, an ingress protection rating of IP40, and a dielectric withstand voltage of 1000V AC. Contact life is rated at 6,000 electrical cycles at 48V DC and 100,000 mechanical cycles. The coil operates with a pickup voltage of 16.8V DC and dropout voltage of 2V DC, with a hold current of 0.45A at 25°C. Torque specifications for the coil terminals are 1.7-2.5 N·m and for the main terminals are 9-11 N·m using a M8 bolt. The part is UL Recognized and meets CCC standards.
