14CUB32BA

The 14CUB32BA is a non-reversing NEMA motor starter from Siemens' Class 14 series, engineered for direct-on-line starting, stopping, and thermal overload protection of industrial electric motors. Designed for 3-pole configurations operating at 600 and managing motor loads up to 4, this heavy-duty starter combines a magnetic contactor with an adjustable overload relay inside a rugged NEMA Type 1 general-purpose enclosure. Electrically, the 14CUB32BA features a heavy-duty magnetic contactor paired with a solid-state or bimetallic overload relay to monitor motor current draw continuously. The protective relay detects phase loss, phase unbalance, and sustained thermal overloads, automatically opening the control circuit to disconnect power before excessive heat can damage motor windings or connected power conductors. Mechanically, the 14CUB32BA is built into a durable, powder-coated sheet steel NEMA 1 enclosure tailored for indoor surface mounting. The interior housing provides ample wiring space with accessible pressure-type screw terminals for straight-through power connection, while reset controls on the enclosure cover allow operators to clear overload conditions safely without opening the cabinet. UL listed and CSA certified, the 14CUB32BA offers an industrial-grade solution for HVAC systems, pumping equipment, conveyor drives, and general machinery control.
