The Allen-Bradley 150-C135NBR is a robust SMC-3 soft starter specifically designed for three-phase motors, operating at a rated voltage range of 200-460V AC with a control voltage of 24V AC/DC. Featuring Delta compatibility, this line-connected controller supports a supply voltage of 480V AC and a frequency of 50-60 Hz with an impressive amperage rating of 135 A, all housed within an open enclosure. Equipped with electronic motor overload and phase reversal protection, the 150-C135NBR ensures safe operation by detecting shorted SCRs and phase imbalances, aborting harmful starts to prevent damage. Key features include an SCR/Run bypass function, LED indicator, and a user-friendly setup with DIP switches and a rotary switch, allowing for quick configuration across five operational modes suitable for a variety of applications like pumps, chillers, and conveyors.
