Schneider Electric GJL36015M03 Mag-Gard Circuit Breaker Series 1

Schneider Electric’s Square D Mag-Gard GJL36015M03 is a three‑pole motor circuit protector (MCP) designed for short‑circuit protection in motor circuits within control panels or motor control centers. The 15 A, 3P device is rated for up to 600Y/347 VAC, making it suitable for many industrial three‑phase motor applications such as conveyors, pumps, and HVAC equipment. It delivers magnetic, instantaneous protection (magnetic‑only trip) with the MAG‑LOC feature that lets you adjust the magnetic trip setting from 3× to 11× the rated current, specifically 45–165 A for this model. This Series 1 GJL unit is UL Recognized, CSA and IEC certified, and offered in unit‑mount construction with a broad range of snap‑in field accessories to tailor protection and signaling in motor control assemblies. The GJL36015M03 is part of the Mag‑Gard family, providing compact, fast-acting short‑circuit protection while pairing with other Square D components designed for motor control panels, HVAC equipment, and industrial automation. By protecting all three phases with a single, magnetically actuated device, it helps safeguard motors against costly fault currents while supporting straightforward panel integration and compatibility with common Mag‑Gard accessories.
