Schneider Electric GFM150HD U Circuit Breaker

GFM150HD is a Micrologic add-on ground-fault module for Schneider Electric's PowerPact H-frame molded‑case circuit breakers, providing ground-fault sensing and relay functions for systems rated from 15 to 150 A. This UL Listed and CSA Certified accessory attaches to an H-frame breaker and requires a shunt trip to enable ground-fault protection. It connects to the breaker via bus-bar terminals at the OFF end, enabling seamless integration without replacing the main device. As part of Schneider Electric's Micrologic ground-fault protection family for PowerPact H, the GFM150HD adds dedicated ground-fault monitoring and relay signaling to help prevent equipment damage from leakage currents.
