Square D ME36800LIG 800A 3-Pole 600 V Circuit Breaker

Introducing the Square D ME36800LIG 800A 3-Pole 600 V Circuit Breaker — a rugged, high-capacity protection device designed for demanding three-phase power systems. With an 800 amp current rating and a 600-volt maximum, this unit is built to guard large feeders and motor circuits in industrial environments. The three-pole design ensures balanced protection across all phases, promoting safer, more reliable operation of heavy equipment and power distribution.

Key specifications

• Current rating: 800 A
• Poles: 3 (three-pole)
• Voltage rating: 600 V
• Part Number: ME36800LIG

Ideal use cases

• Industrial power distribution panels and main feeders in manufacturing facilities
• Motor feeders for heavy equipment, conveyors, and processing lines
• Three-phase service panels in commercial and light industrial settings requiring robust overcurrent protection

Why it matters

The ME36800LIG delivers reliable overcurrent protection for large, three-phase electrical systems. In the event of a fault, it interrupts power to prevent damage to cables, motors, and downstream equipment, helping minimize downtime and expensive repairs. The three-pole design ensures simultaneous disconnection of all phases, preserving system balance and reducing the risk of phase-to-ground faults.

Installation and practical considerations

Designed for integration into compatible Square D panels and distribution systems, this breaker should be installed following the manufacturer’s guidelines and local electrical codes. Verify proper fit within your panel, ensure correct mounting, and observe torque and installation instructions to maintain safe, long-lasting protective performance.

For professionals seeking a dependable, high-capacity solution for 3-phase power protection, the Square D ME36800LIG 800A 3-Pole 600 V Circuit Breaker offers precise, scalable protection for demanding industrial applications.
