Siemens BF250AH - 50 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Meet the Siemens BF250AH: a dependable 50A, 240V, 2-pole bolt-on molded case circuit breaker built to safeguard panelboards and loadcenters from overcurrent and short-circuit faults. This isn’t just a breaker—it’s a critical component that keeps electrical systems safe, quiet, and performing at their best.

Why the BF250AH stands out

• Secure bolt-on mounting for a rigid, vibration-resistant bus connection. In busy electrical rooms or panels that experience movement, this design stays seated and maintains a solid electrical path.
• Thermal-magnetic trip unit delivers stable, repeatable protection performance by combining thermal overload sensing with magnetic short-circuit protection. Expect consistent trips that protect wiring and devices even as ambient temperatures shift.
• OEM-compatible design that works with matching Siemens panelboards and loadcenters, ensuring proper fit, alignment, and electrical performance when you pair components from the same family.
• Versatile across environments ideal for residential, commercial, and light industrial applications where reliable branch-circuit protection is essential.

The BF250AH is engineered to protect your electrical distribution without compromising serviceability. Its 2-pole configuration provides clear, coordinated protection for multi-wire branch circuits, while the molded-case construction offers robust insulation and durability in varied settings—from tight utility rooms to expansive commercial pantries.
