MH36600 - 600 Amp Circuit Breaker

MH36600 - 600 Amp Circuit Breaker

The MH36600 molded-case circuit breaker from Schneider Electric’s PowerPacT M line offers dependable, high-capacity circuit protection for demanding installations. Designed to guard your electrical infrastructure from overloads, faults, and short circuits, this 3-pole, 600 A breaker provides strong performance without overcomplicating installation or operation. Whether you’re managing power in an industrial plant, commercial facility, or heavy-duty distribution panel, the MH36600 is engineered to deliver peace of mind and long-term reliability.

Key Features and Benefits

• High fault-clearing capability: rated at 25 kA at 600 VAC (and up to 65 kA at 480 VAC or 65 kA at 240 VAC), it keeps your system safer under severe fault conditions.
• Electronic trip control (ET 1.0): its built-in ET 1.0 trip unit ensures accurate, adjustable protection so you're not relying on coarse thermal/magnetic mechanisms alone.
• Manual trip override: the push-to-trip button lets you safely test or open the circuit on demand.
• Busbar-ready mounting: with unit-mount (busbar) compatibility, installation is more straightforward and wiring paths remain clean.
• 80% continuous rating: supports efficient operation without oversizing your conductors.

Material Compliance and Certifications

• This breaker complies with globally recognized safety and performance standards, including UL and CSA certification, IEC-60947-2 compatibility, and CE marking where relevant. It meets a pollution degree of 3 per IEC-60947-1, making it suitable for typical industrial or commercial indoor environments.
• The device is also ROHS-compliant and conforms to applicable environmental regulations in its materials and manufacturing.

Where It Works Best

• The MH36600 shines in situations where you need dependable protection in heavy-duty power distribution systems — for example, as a main feeder breaker or in switchgear assemblies in manufacturing plants, data centers, large commercial buildings, or critical infrastructure. Because it allows isolation per IEC standards, it’s also suitable in switchboard configurations when you need to visually and physically separate circuits for maintenance.
