Siemens | BF250 | Circuit Breaker | 50A | 2-Pole | 240V | 10kA | Bolt-On

Meet the Siemens BF250 circuit breaker—a precise, bolt-on solution built for demanding 50A, 2-pole, 240V circuits. With a robust 10 kA interrupting capacity, this unit is engineered to protect valuable equipment and wiring in retrofit, maintenance, and replacement projects. When you need reliable overcurrent protection in a Siemens-compatible panel, the BF250 delivers consistent performance and straightforward serviceability.

Key specifications

• Amperage: 50A
• Poles: 2-Pole
• Voltage: 240V
• Interrupting rating: 10 kA
• Mounting style: Bolt-On
• Reference: Part number BF250 for compatibility checks

Why this BF250 stands out

• Secure, bolt-on mounting designed for durable connections in compatible panels, reducing the risk of loose contacts over time.
• High interrupting capacity (10 kA) provides robust protection for high-demand 240V circuits, helping to prevent damage during fault conditions.
• Part-number precision (BF250) makes sourcing and cross-reference straightforward, minimizing downtime during replacements or upgrades.
• Specifically suited for maintenance, retrofit, and replacement projects where matching Siemens specs is essential, ensuring reliable operation within the system.

Ideal use cases

• Upgrading or replacing a 50A, 240V circuit in residential, commercial, or light industrial panels that accept a two-pole bolt-on breaker.
• Retrofits where existing equipment relies on Siemens BF-series compatibility, providing seamless integration with minimal panel modification.
• Spare-breaking capacity for service crews performing scheduled maintenance, ensuring quick swaps that keep critical loads online.
• Protection for high-draw appliances and equipment such as large HVAC components, water heaters, or other 240V loads that require solid, dependable overcurrent protection.

Compatibility and installation notes

Before ordering, confirm that your panel accepts BF250-style bolt-on breakers and that the overall system ratings align with a 50A, 240V, 10 kA protection scheme. The BF250’s two-pole design is intended to simultaneously interrupt both live conductors, delivering comprehensive protection for the circuit it guards. For installation, rely on your panel manufacturer’s torque and mounting guidelines, and ensure the power is fully disconnected during service.

Practical guidance for buyers

• Use the BF250 as a precise reference point when sourcing replacements or upgrades to maintain electrical safety and code compliance.
• Keep a compatible spare BF250 on hand for quick maintenance swaps, reducing panel downtime during service windows.
• When in doubt about fit, match the part number BF250 and verify panel compatibility rather than relying solely on amperage or voltage ratings.
