The DCNLJ250NB12-01 is a normally open, single-pole, single-throw DC contactor rated for 250A continuous current, with main contacts designed for 48V typical and 60V maximum operation using a 12V DC coil. It features non-polarized contacts, an IP40 ingress protection rating, and operates within a temperature range of -40°C to +85°C. The device has a mechanical life of 3,000,000 operations and an electrical life of 100,000 operations at rated voltage. It weighs 776 g and uses a side-mounting configuration with M10 bolt terminals requiring 9 to 11 N·m torque. The contact voltage drop is ≤50 mV at 100A, and it has a dielectric withstand voltage of 1000V AC. An auxiliary contact is not included.
Designed for high-current contact switching in electric control systems of communication power supplies, electro-motion forklifts, motor cars, trains, uninterruptible power supplies (UPS), and more, this 250A High-Current High-Voltage DC Contactor is a normally open relay with a contact voltage drop of ≤50 mV @ 100A and a 1600A 5 ms make-break rating.This model of the DCNLJ250 series high-voltage contactor (DCNLJ250NB12-01) features non-polarized contacts rated for 48V (typical) and 60V (max) and a 12V coil. Main contacts are rated for 48V (typical) and 60V (max) 12V coil rating Non-polarized contacts
