The DCNLM100NB48 is a 100A continuous, normally open, side-mount DC contactor relay with a 48V coil voltage and 60V DC max contact rating. It features non-polarized main contacts, no auxiliary contacts, and a single-coil design. Contact voltage drop is ≤80mV at 100A. Operating temperature ranges from -40°C to +70°C. Electrical life is 6,000 cycles at 48V DC; mechanical life is 100,000 cycles. Coil pickup voltage is 33.6V, dropout is 4V, and hold current is 0.08A at 25°C. Mounting requires M6 bolts tightened to 4-6 N·m for main terminals and M4 bolts with 1.7-2.5 N·m for coil terminals. Ingress protection is IP40, and dielectric strength is 1,000V AC.
The DCNLM Series 60V High-Current DC Contactor Relay features 100A 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 (DCNLM100NB48) features 60V non-polarized main contacts and a single-coil design. 100A continuous current rating for high-current contact switching 48V coil rating Single-coil relay design
