Schneider Electric MG24544 40A 3-Pole 240 V Circuit Breaker

Schneider Electric MG24544 40A 3-Pole 240 V Circuit Breaker is a robust protection device designed to deliver reliable overcurrent protection in 240-volt distribution systems. With a 40-amp rating and three poles, it’s tailored for safeguarding multi-wire or three-phase circuits in commercial, industrial, and larger residential installations.

Why this breaker stands out: it combines Schneider Electric's engineering precision with a form factor that fits Schneider panels and bus systems, delivering consistent tripping performance and dependable protection when it matters. The 3-pole design ensures synchronized disconnection across all active conductors, helping prevent dangerous shared-neutral faults and equipment damage.

Key features and benefits

• Current rating: 40 A — targeted protection for high-demand circuits while minimizing nuisance trips during normal operation.
• Poles: 3 — ideal for 3-phase electrical distribution or multi-wire branch circuits requiring simultaneous disconnection.
• Voltage rating: 240 V — suitable for standard 240V distribution boards common in commercial and some residential environments.
• Designed for reliable performance within Schneider Electric ecosystems, ensuring compatibility with existing panels, accessories, and protective devices.
• Simple, predictable replacement within compatible Schneider Electric systems, reducing downtime during maintenance or upgrades.

Ideal use cases

The MG24544 is well-suited for:

• Three-phase power distribution in commercial spaces, workshops, and light-industrial facilities needing solid overcurrent protection at 240V.
• Large residential or multi-tenant installations where a single 240V circuit requires dedicated protection across multiple conductors.
• Panel upgrades or replacements within existing Schneider Electric infrastructures, providing consistent performance with other Schneider devices.

Installation and safety considerations

As with all electrical protective devices, installation should be performed by a qualified electrician. Verify panel compatibility, follow the manufacturer’s installation guidance, and ensure proper terminations per standard electrical codes. The MG24544 is designed to integrate smoothly with Schneider Electric distribution panels and accessories, helping you maintain a cohesive, safer electrical system.
