The 17CP92BF1181 is a combination non-reversing NEMA Size 0 motor starter unit from Siemens, engineered for full-voltage across-the-line motor control paired with localized branch circuit disconnect protection. Designed for 3-pole systems operating at 600 with an adjustable motor current range of 18, this integrated unit combines a heavy-duty magnetic contactor, an ESP200 solid-state overload relay, and a thermal-magnetic molded case circuit breaker housed within a NEMA Type 1 general-purpose enclosure. Electrically, the 17CP92BF1181 delivers comprehensive branch circuit and motor winding protection. Its integrated circuit breaker acts as the primary short-circuit and instantaneous fault disconnect, while the ESP200 overload relay continuously monitors line current to protect against phase failure, phase unbalance, and sustained thermal overloads. This dual-protective assembly quickly interrupts fault conditions, preventing thermal degradation of power wiring and downstream industrial equipment. Mechanically, the 17CP92BF1181 is built into a heavy-duty sheet steel NEMA 1 enclosure designed for indoor wall-mounting applications. The cabinet features an externally operable flange-mounted disconnect handle that remains mechanically interlocked with the enclosure door to prevent access while energized, alongside cover-mounted pushbuttons for local control and manual overload resetting.
