Square D MGL36800E10 Molded Case Circuit Breaker

The Square D MGL36800E10 is a PowerPact M‑Frame molded‑case circuit breaker rated for 800 A, three poles, and 600 V AC, featuring an electronic trip and an 18 kA short‑circuit interruption rating at 600 V. It uses line and load lug terminals for straightforward integration into electrical distribution systems and carries an 80% continuous‑load rating, making it suitable for high‑current feeder protection in demanding installations. This model is part of Schneider Electric’s PowerPact M family (MGL36400, MGL36600, MGL36800E10), which covers a 300–800 A range of high‑capacity MCCBs designed for industrial power protection. When operating at lower voltages, the device’s interrupting capacity scales—up to 65 kA at 240 VAC and 35 kA at 480 VAC—providing flexibility across different service voltages while maintaining robust protection for feeders and main circuits. The MGL36800E10 is specified for 600 VAC service with three poles and an adjustable electronic trip, aligning with common needs in large‑scale electrical distribution where reliable coordination with protective relays and upstream devices is important.
