Product Description
The Allen-Bradley 150-C85NBR is an 85-Ampere SMC-3 Smart Motor Controller, also known as a Soft Starter, designed for 200-460VAC, 3-Phase motors. It provides configurable soft start and stop functions (Soft Start, Kickstart, Current Limiting, Coast to stop, and Soft-stop) to protect motors by limiting inrush current and mechanical stress. Features include adjustable start times, initial torque (up to 65% locked rotor torque), and current limiting based on Full Load Current (FLA), along with selectable overload trip class. It operates with 24VDC/24VAC control voltage and supports both line and Delta-connected motors. The open-type controller includes assignable N.O. auxiliary contacts for OVLD/FLT and Normal/Up-to-Speed feedback. It offers robust circuit protection and withstands specific voltage, vibration, shock, and environmental conditions, including altitude, temperature, and humidity. It is certified by CE, c-UL-us, CSA, and CCC and measures 2.83 x 8.11 x 5.12 inches.
Is Your Device Showing These Signs?
The Allen Bradley 150-C85NBR commonly exhibits issues such as failed overload relays causing motor tripping, contactor coil burnout leading to operational failure, and worn or damaged contacts resulting in increased resistance and voltage drop. Troubleshooting often reveals thermal overload settings improperly configured, insufficient control voltage impacting coil performance, and environmental contamination accelerating contact degradation. Replacement of the overload relay, contactor coil, or complete contactor assembly resolves these problems, ensuring proper motor control and protection. Regular inspection and adherence to recommended maintenance schedules prevent future failures.
