Schneider Electric M9F22450 - 50A, 4-Pole, Circuit Breaker

Schneider Electric M9F22450 is a 50A, 4-pole circuit breaker engineered for dependable overcurrent protection in demanding electrical systems.

Its 4-pole design supports true three-phase protection with a neutral, enabling simultaneous disconnection of all conductors to maximize safety during fault conditions. This makes it well suited for panelboards, switchboards, and control panels in industrial, commercial, and OEM applications where uptime and safe operation are essential.

Product highlights

• Current rating: 50 A
• Poles: 4-Pole
• Breaker type: Circuit Breaker
• Applications: panelboards, switchboards, control panels, motor control centers
• Configuration: supports 3-phase systems with neutral disconnection for comprehensive protection

Why it stands out

In environments where electrical distribution supports critical equipment, the M9F22450 delivers reliable, predictable response to overcurrents, protecting wiring, drives, and motors from damage. Built to withstand the rigors of industrial spaces, this breaker minimizes nuisance trips and simplifies maintenance through straightforward mounting and wiring practices, all while integrating smoothly into Schneider Electric ecosystems.

Ideal use cases

• Industrial facilities and manufacturing lines needing robust 50A protection for feeders and motors
• Commercial equipment racks and distribution panels requiring safe, code-compliant shutdowns
