Square D MGL36800E10 800A 3-Pole 600 V Circuit Breaker

Square D MGL36800E10 is an 800A, 3-pole, 600V circuit breaker built for demanding three-phase power distribution. Designed to protect large motors, feeders, and main service circuits, this unit delivers the trusted reliability that industrial and commercial panels rely on.

• Part Number: MGL36800E10
• Current rating: 800 A
• Poles: 3
• Voltage rating: 600 V
• Three-pole construction: synchronized disconnection of all three phases to protect three-phase equipment
• Compatibility: designed for use in compatible Square D panels and enclosures

This 3-pole breaker consolidates protection for three phases into a single device, simplifying wiring and maintenance while delivering coordinated tripping across all conductors. It’s particularly well-suited for main service disconnects, heavy motor circuits, and large distribution feeders in industrial settings, as well as commercial facilities with substantial three-phase loads.

Why this matters: with an 800A rating, it handles substantial service or equipment currents without sacrificing rapid and reliable interruption during fault conditions. The 600V rating matches many industrial and commercial distribution systems, providing robust protection and peace of mind for critical infrastructure.

Who it’s ideal for: facilities with heavy three-phase equipment, such as manufacturing lines, large pumps or HVAC systems, conveyors, and other high-current loads that require a centralized, three-pole protection solution.

Practical tips for use:

• Ensure your panel and enclosure are rated for 800A and compatible with a 3-pole, 600V device.
• Verify the part number (MGL36800E10) matches your order and that installation adheres to listing requirements and applicable electrical codes.
• Use this breaker to achieve synchronized protection across all three phases, reducing the risk of phase imbalance and equipment damage during faults.
