Square D MHP36800 Molded Case Circuit Breaker

Square D MHP36800 Molded Case Circuit Breaker is a three‑pole PowerPact molded‑case protective device rated for 800 A at 600 V AC, designed for industrial feeders and main protection in power‑distribution panels. This MasterPact family MCCB (variants in the PowerPact line such as MGP/MGA/MGF) carries a 600 V AC / 250 V DC rating and delivers interrupting capabilities of 18 kA at 600 VAC, 65 kA at 240 VAC, and 35 kA at 480 VAC, depending on system voltage. The unit can be configured with an electronic trip unit for precise protection against overloads and short circuits, aligning with heavy‑duty industrial applications. With its 3‑pole design, it provides robust protection for large loads and feeders in commercial and industrial environments, and is compatible with Square D PowerPact enclosures and panelboards that accept M‑Frame breakers. Typical applications include main feeders from service equipment, motor control centers, and large distribution panels where high ampacity and reliable interruption performance are required, while meeting 600 VAC electrical distribution standards.
