Schneider Electric GA12TPM Ground Fault Sensor

Schneider Electric GA12TPM Ground Fault Sensor (Square D GA12TPM) is a dedicated ground-fault sensing device for AC power circuits in industrial environments, engineered to detect ground fault conditions and initiate protective actions within safety-critical electrical systems. It operates on a nominal 102–132 VAC and specifies a 2 A fuse rated for 250 V, providing clear, verifiable electrical characteristics for coordinating protection in industrial feeders and panel installations. As part of Schneider Electric's Square D lineup, the GA12TPM is designed to integrate with existing protection schemes across industrial electrical assemblies to deliver targeted ground-fault sensing without introducing ambiguity in fault signaling. The GA12TPM remains a core element within the Square D protection ecosystem, a sensor intended for use alongside other Square D protection devices to form a coherent ground-fault protection strategy for industrial applications.
