Siemens B215HH - 15 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Meet the Siemens B215HH — a purpose-built 15A, 240V, 2-pole bolt-on molded case circuit breaker designed to deliver reliable branch circuit protection in panelboards and load centers. Built to handle everyday electrical loads with confidence, this breaker is ready to shield residential, commercial, and light industrial circuits from overcurrent and short-circuit events.

• Secure bolt-on mounting provides a rigid, vibration-resistant connection to the bus, reducing movement and ensuring consistent electrical contact in demanding environments.
• Thermal-magnetic trip unit delivers stable, repeatable protection: the thermal element responds to sustained overloads, while the magnetic element snaps to action on high-energy faults for fast isolation.
• OEM panel compatibility designed to work seamlessly with matching Siemens load centers and panelboards, helping you maintain proper fit, electrical characteristics, and coordination.
• Versatile applications ideal for residential, commercial, and light industrial electrical setups that require dependable 2-pole 240V protection on branch circuits.

Why choose this breaker? It’s not just about meeting a spec sheet—it’s about delivering measurable reliability where it matters most. The 2-pole design protects both conductors in 240V circuits, making it a practical choice for dual-hot loads, multiwire branch circuits, and common equipment like pumps, fans, or small HVAC components that require solid protection. The bolt-on construction reduces the risk of loosening over time in environments with vibration or movement, helping you maintain consistent protection without frequent adjustments.

Who is this ideal for? Electricians, facilities managers, and homeowners maintaining Siemens panelboards and load centers will appreciate the precise fit, predictable trip behavior, and straightforward replacement from the B215HH. When you need a dependable, exactly-rated solution that aligns with existing Siemens gear, this breaker stands out as a practical, long-term choice.

Practical tips for use

• Confirm that your panelboard or load center is compatible with the B215HH and supports a 15A, 240V, 2-pole bolt-on breaker.
• Use this breaker to protect individual 240V circuits or multiwire branches that require simultaneous shutoff of both hot legs.
• When replacing an existing breaker, ensure the trip characteristics and mounting style match your panel’s specifications to maintain proper coordination and safety.
• Keep a legacy of reliable electrical protection by pairing with correctly rated conductors and compliant enclosure hardware.

The Siemens B215HH is more than a component; it’s a confident choice for safe, dependable electrical protection that fits seamlessly into established Siemens panel ecosystems and delivers clear, practical benefits in real-world installations.
