Allen-Bradley 150-C3NBD Industrial Control Panel Mount Relay

Allen-Bradley 150-C3NBD is a panel-mount Soft Starter in the SMC-3 family designed to start and protect three-phase motors by controlling voltage during ramp-up. It employs TB-97/TB-98 control-circuit signaling with an electromagnetic relay for auxiliary contacts to indicate overload or fault conditions, making status monitoring straightforward within a control panel. The unit is rated for 460 V AC three-phase operation and delivers about 1.1 kW of motor power, enabling a smoother, in-rush-limited start that reduces mechanical stress and electrical disturbance on the driven equipment. With an IP2X enclosure rating, it is suited for installation in standard industrial panels where basic protection is required. Typical applications include conveyors, pumps, and fans where controlled starting, overload protection, and fault signaling are essential, and it integrates with common motor-control architectures in manufacturing and process environments.
