Siemens BF115H - 15 A, 120 V, 1-Pole Bolt-On Circuit Breaker | AmpState

Designed for dependable branch circuit protection, the Siemens BF115H is a 1-pole, 15A, 120V bolt-on molded case circuit breaker built to endure vibration and deliver consistent protection in panelboards and load centers.

Why the BF115H stands out

• Rigid, vibration-resistant bus connection through secure bolt-on mounting, ensuring a durable, stable installation that resists loosening over time.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining overload (thermal) sensing with fast short-circuit response (magnetic) for real-world reliability.
• OEM-compatible design engineered to mate with matching Siemens panelboards and load centers, simplifying installation and maintenance while preserving protective coordination.
• Versatile for a range of applications ideal for residential, commercial, and light industrial circuits that require reliable single-pole protection.

How it fits into your electrical system

The BF115H provides single-pole, 15-ampere protection at 120V, making it well-suited for protecting individual branch circuits in home panels, small offices, or service spaces. Its molded-case construction adds durability for everyday use, while the bolt-on mounting supports straightforward installation in compatible panels.
