Square D FAL36050 - 50 A, 600 V, 3-Pole Circuit Breaker | AmpState

Square D FAL36050 is a 50 A, 600 V, 3-pole molded-case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Available from AmpState, this authentic unit is built to integrate seamlessly with matching OEM environments and components.

Why this design stands out: the compact molded-case construction makes efficient use of valuable panel space, enabling cleaner layouts in crowded enclosures. The thermal-magnetic trip unit provides stable, repeatable protection by combining a thermal element for gradual overloads with a magnetic element that responds instantly to severe faults. This dual-response approach helps minimize nuisance trips while safeguarding sensitive equipment.

• Amperage rating: 50 A
• Voltage rating: 600 V
• Poles: 3
• Type: Thermal-magnetic molded-case circuit breaker (MCCB)
• Manufacturer: Square D
• Part number: FAL36050
• Application: Branch circuit overcurrent and short-circuit protection

Ideal applications

This 3-pole MCCB is well-suited for residential, commercial, and light industrial installations where reliable protection is essential. Use it in panelboards and load centers that accept Square D molded-case breakers to guard multi-wire and three-phase circuits, including feeders to subpanels, HVAC equipment, lighting racks, and other heavy-load loads.

What makes it different

Rather than a one-size-fits-all solution, the FAL36050 offers OEM-aligned compatibility and a proven protection strategy that balances space efficiency with robust safety. The combination of thermal and magnetic trip technology provides predictable response curves, reducing downtime and equipment wear compared with simpler trip mechanisms.

Practical tips for using this breaker

Verify your panelboard or load center accepts Square D molded-case breakers in the FAL family before installation. Follow Square D’s installation guidelines for mounting and grounding, and ensure any maintenance window includes a quick replacement plan with a spare unit on hand to minimize service interruptions.
