Allen-Bradley 150-C43NBR Momentary Push Button Switch

Allen-Bradley 150-C43NBR is a three‑phase soft starter from Rockwell Automation’s SMC‑3 family. Configured as a 3‑wire, open‑type device, it provides motor-start control for 3‑phase induction motors rated up to 43 A and 460 V, delivering soft‑start capabilities that help limit inrush and extend motor life (roughly 22 kW at 460 V). The unit includes embedded motor overload protection with DIP‑switch selectable trip classes (10, 15, or 20) and a Hold To Test/Push To Reset button for fault diagnostics. With 50/60 Hz operation and IP2X protection, it is suitable for open‑enclosure installations in industrial environments where space is at a premium and reliable motor control and protection are required. The 150‑C43NBR integrates with standard Rockwell Automation control architectures, offering a compact solution for starting, stopping, and safeguarding motors in applications such as conveyors, pumps, and fans.
