Cutler-Hammer 6633C29G03 Current Sensor Module

The Cutler-Hammer 6633C29G03 current sensor module, referenced in some catalogs as Cutler Hammer LGFCT400, is an L-frame device engineered for current measurement on a single conductor within electrical panels and control cabinets. The specification "Current Ratio 400:0.06" defines the device's sensing relationship, enabling integration into instrumentation or protection schemes that require scaled current readings. The 6633C29G03 designation identifies this specific sensor module, assisting technicians in ordering and cross-referencing parts. Its L-frame footprint supports compact installation beside power distribution components, while its dedicated sensing path provides a stable input for process instrumentation or protective relays. By pairing this module with compatible interface electronics, engineers can monitor load current trends, detect overload conditions, and inform control logic or metering systems. The LGFCT400 label situates the device within its current-ratio family, simplifying maintenance planning and part replacement within legacy Cutler-Hammer systems.
