Product Description
The Allen-Bradley 150-A850NBD, part of the Bulletin 150 SMC PLUS series, is an open-type, microcomputer-controlled solid-state motor controller for three-phase induction motors. It offers energy savings with a built-in feature that optimizes efficiency during periods of light or no load, eliminating the need for external wiring and extra panel space. This 850A controller, rated for 10-700 HP motors and 200-480VAC, supports Soft Start, Soft Start with Kickstart, Current Limit Start, and Full Voltage Start modes. Suitable for both motor and resistive loads, it weighs 370 lbs and measures 60.00 x 32.00 x 15.83 inches. It is cULus Listed, CE marked, CCC certified, CSA certified, and compliant with CSA C22.2 No.14, EN/IEC 60947-1, EN/IEC 609947-4-2, and UL 508 standards.
Is Your Device Showing These Signs?
The Allen Bradley 150-A850NBD commonly experiences issues such as failed solid-state overload relays, resulting in motor protection faults and nuisance tripping. Contactor coil burnout is a frequent problem, leading to operational failure and preventing motor starts. Auxiliary contact block malfunctions disrupt signaling and control circuits. Terminal block damage from over-tightening or corrosion causes connection failures and intermittent operation. Firmware corruption within the electronic overload can also occur, necessitating a reflash or replacement to restore proper functionality and communication on the network.
