Square D MAL36800 - 800 A, 3-Pole Circuit Breaker | AmpState

Square D MAL36800 is an 800 A, 3-pole molded case circuit breaker designed for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers.

Its compact molded case design makes the most of panel space, while the thermal-magnetic trip unit delivers stable, repeatable protection by combining overload sensing with instantaneous short-circuit response. This means fewer nuisance trips and faster isolation of faults, helping protect wiring, devices, and all downstream equipment.

• 800 A, 3-pole capacity for high-demand branches and large feeders
• Thermal-magnetic trip provides layered protection—thermal for sustained overload, magnetic for rapid short-circuit disconnection
• Compact form factor saves panel space and simplifies panel layout
• OEM-compatible engineered to fit and coordinate with matching Square D OEM load centers and panelboards
• Versatile across sectors suitable for residential, commercial, and light industrial installations

Typical use cases include serving as a main breaker or feeder device in large distribution panels, upgrading panels to support higher ampacity circuits, and protecting critical feeders in commercial or light industrial equipment racks.
