Square D 9007 CO54 USNT Circuit Breaker Module

Square D 9007CO54 USNT is a plug-in limit switch unit designed for use with the 9007C family of heavy-duty limit switches in industrial automation. The zinc alloy housing measures about 4.2 inches long and serves as a plug-in sub-assembly for 9007C bodies, providing a robust interface for a normally open/normally closed contact pair. It uses a SPDT arrangement (1NO-1NC) and is rated for up to 600 VAC at 10 A, and up to 600 VDC at 2.5 A, with ratings suitable for safety circuits and control circuits in harsh environments. The unit carries UL, CSA, and CE certifications and is compatible with NEMA enclosures 1/2/4/6/6P/12/13 and with ingress protection levels IP65, IP66, and IP67, ensuring protection against dust, water, and harsh wash-downs in industrial settings. The 1/2 in NPT RACCORD threaded connection supports secure mounting and linkage with standard 9007C actuators, while still offering reliable, field-replaceable plug-in operation. Typical applications include automation machinery such as conveyors, packaging lines, presses, and other equipment requiring a dependable limit-switch interface that can be quickly replaced without full disassembly. This model is an established option when a robust plug-in limit switch module is required in rugged environments, delivering dependable actuation and straightforward wiring within Schneider Electric's Square D line.
