The 150-C30NBR is part of Rockwell Automation’s Bulletin 150 SMC-3 smart motor controller family, providing a cost-effective solid-state soft starter for small and medium three-phase induction motors. It supports line voltages from 200…460 V AC, 3‑phase, 50/60 Hz, with a 30 A current rating and 24 V AC/DC control voltage, in an open IP2X enclosure for panel mounting. With line-connected motors, it covers an output current range of 10–30 A and power range up to 20 HP (≈15 kW) at 400–460 V; in inside‑delta configurations it can handle up to 22 kW / 10–30 HP depending on wiring.
The controller offers several starting and stopping methods: Soft Start, Kickstart, Current Limit, Coast to Stop, and Soft Stop, helping reduce mechanical stress and inrush current during motor starts and stops. Integrated protection includes programmable electronic motor overload, over-temperature monitoring of SCRs, and coordination with external fusing (Class J/L/CC up to 60 A) and circuit breakers. It also provides auxiliary contacts for status indication, including one NO contact for overload/fault and one NO contact for normal/up‑to‑speed status, allowing easy integration into control circuits and PLCs.
Designed for applications such as compressors, chillers, pumps, conveyors, and crushers, the 150-C30NBR operates from -5…55 °C at 5–95% non‑condensing humidity, with shock resistance to 15 g and vibration to 1 g up to 2000 m altitude. It meets UL, CSA, CE, CCC and other global standards, making it suitable for international installations.
