Product Overview

The Allen-Bradley 150-C3NBR is an open-type SMC-3 smart motor controller for single-direction motor starting and stopping. Part of the SMC-3 family, it provides soft-start, soft-stop, internal bypass and adjustable parameters such as kick-start, initial torque and overload trip class. In a control system, it reduces mechanical and electrical stress during motor start-up and shutdown. Typical applications include small three-phase motors up to approximately 3 A, such as pump drives, conveyor motors, and general machinery requiring controlled acceleration and deceleration.
