The DCNLM50NB60 is a 60V DC maximum, normally open, single-coil contactor relay with a 50A continuous current rating and a 60V coil voltage, designed for stationary applications such as communication power supplies and uninterruptible power supplies. It features non-polarized main contacts, side mounting, and an ingress protection rating of IP40. The operating temperature range is -40°C to +70°C, with a dielectric withstand voltage of 1000V AC and an insulation resistance of at least 50MΩ at 500V DC. The contactor has a mechanical life of 100,000 cycles and an electrical life of 6000 cycles at 48V DC. Terminal torque specifications are 4-5N·m for main contacts, 1.7-2.5N·m for coil terminals, and use an M5 bolt for mounting.
The DCNLM Series 60V DC Contactor Relay features 50A contact switching capability with a 60V 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 DC contactor (DCNLM50NB60) features 60V non-polarized main contacts. 50 A continuous current rating 60 V coil rating
