MHL36500 - 500 Amp Circuit Breaker

MHL36500 - 500 Amp Circuit Breaker

When your system demands a heavy-duty, dependable protector, the MHL36500 molded case circuit breaker steps in. Built by Schneider Electric / Square D, this 3-pole, 500-amp unit is designed to deliver stable, continuous protection in industrial, commercial, and mission-critical environments. It operates at ratings up to 600 VAC and offers excellent fault-clearing and environmental compliance through its Green Premium designation. In short, it combines high current capacity, safety, and sustainable design in one compact package.

Key Features and Benefits

• High current capacity: Rated for 500 A, it handles severe load demands without breaking a sweat.
• Strong fault protection: With a breaking capacity of up to 25 kA (and higher in other voltage conditions), it can interrupt faults swiftly before damage occurs.
• Three-pole design: Ensures balanced protection across all phases in three-phase systems.
• Compact footprint: Though built for power, its design stays efficient in space and integrates easily into existing breaker assemblies.
• Eco-aware build: As part of the Green Premium line, it meets strict environmental criteria, including lower lifecycle carbon footprint and material transparency.
• Built for longevity: Solid construction and durable engineering support long service life with minimal maintenance.
