Siemens | ED41B050 | Circuit Breaker | 50A | 1-Pole | 277V

Meet the Siemens ED41B050 Circuit Breaker — a 50-amp, single-pole protective device designed to safeguard 277-volt circuits in commercial and industrial settings. Engineered for maintenance, retrofit, and replacement projects where precise specifications matter, this breaker delivers reliable performance and a straightforward install in compatible Siemens panels.

Key specifications

• Amperage: 50A
• Poles: 1-Pole
• Voltage: 277V
• Part number: ED41B050

Compatibility and selection tips: This part number is the best reference for compatibility. Always confirm fit and ratings before ordering to ensure the breaker matches your panel model and the circuit it will protect.

Why choose this Siemens 1-pole breaker?

• Precise 50A protection for individual circuits in 277V systems—ideal for commercial lighting, feeder circuits, and equipment running on 277V distribution networks.
• Single-pole design keeps installations simple when you need dedicated protection for a single conductor path, reducing complexity in panel layouts.
• Siemens engineering offers consistent, predictable trip performance across maintenance cycles and retrofit projects.

Use cases and installation scenarios

Common applications include replacing aging breakers in existing Siemens panels, retrofitting power distribution to handle new loads, or upgrading a circuit that requires 50A protection at 277V. This breaker is especially well-suited for commercial environments with 277V lighting or equipment feeders where reliable, certified replacements matter.

Practical considerations

• Plan your replacement by verifying panel compatibility and ensuring the 1-pole, 50A, 277V configuration aligns with the target circuit.
• Keep the ED41B050 as the reference point for future maintenance or ordering to avoid mismatches.
• Store spare breakers in a controlled environment to prevent corrosion and ensure clean contacts during installation.
