Schneider Electric MJA36600 Circuit Breaker

Schneider Electric's PowerPact MJA36600 is a 3-pole molded‑case circuit breaker in the PowerPact M frame, rated for 600 A at 600 V, with an I‑Line plug‑in mounting for use in compatible PowerPact M distribution panels. It provides a short‑circuit interrupting capacity of 25 kA at 600 VAC and uses an ET 1.0 electronic trip unit with an 80% continuous‑load rating. This 600 A, 3‑pole device protects feeders and motor circuits in industrial and commercial power systems and is typically used with I‑Line panelboards and switchboards to deliver coordinated protection across a distribution scheme. As part of the PowerPact line, it shares mounting and accessory compatibility with other M‑frame breakers, simplifying replacement and expansion in large electrical rooms.
