Square D | MEL36800LSG | Circuit Breaker | 800A | 3-Pole | 600V

The Square D MEL36800LSG circuit breaker delivers rugged, high-capacity protection for demanding industrial power systems. Rated for 800A, with a 3-pole configuration and a 600V maximum, this unit is built to safeguard large feeders, motor circuits, and panelboards from overloads and short circuits. Designed for maintenance, retrofit, and replacement projects where exact specifications matter, the MEL36800LSG remains the trusted reference for compatibility—the part number itself is your best guide when matching to panels and MCCBs.

• Three-pole protection ensures balanced fault protection across all three phases in a 3-phase system, reducing the risk of uneven loading and equipment damage.
• 800A rating supports high-load environments, enabling reliable operation of heavy machinery and large feeders without unnecessary trips.
• 600V voltage rating fits standard industrial distribution networks, making it suitable for a wide range of facilities and applications.
• Genuine Square D reliability and the assurance of spare-part availability simplify maintenance and long-term serviceability.
• Clear compatibility reference by using the MEL36800LSG part number to confirm fit with your panel, MCCB lineup, or switchgear before installation.

• Ideal use cases include retrofits in legacy Square D panels where the MEL36800LSG matches existing specifications, replacement for aging circuit breakers in large feeders, and maintenance upgrades in facilities with high-current motors and conveyors.
• Perfect for new installations requiring robust three-phase protection at 600V in manufacturing plants, data centers, and other industrial environments.

Before ordering, ensure your system expects an 800A, 3-pole, 600V device and that the MEL36800LSG aligns with your panel’s frame, bus type, and rating. The part number is the most reliable reference for compatibility, and cross-checking with your panel documentation will help prevent misfits during replacement or retrofitting.
