Siemens B130HH - 30 A, 120 V, 1-Pole Bolt-On Circuit Breaker | AmpState

Meet the Siemens B130HH—a purpose-built 30A, 120V, 1-pole bolt-on molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built by Siemens and sold by AmpState, this device delivers reliable performance where it matters most: in homes, offices, and light industrial settings.

Why the B130HH stands out

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, reducing the chance of loose contacts and nuisance trips in environments with equipment vibration or panel movement.
• Thermal-magnetic trip unit delivers stable, repeatable protection across a wide temperature range, helping to prevent both nuisance trips and delayed responses to faults.
• 1-pole, 30A, 120V design is ideal for protecting individual branch circuits or feeders within standard panelboards and load centers.
• OEM compatibility designed to integrate smoothly with matching Siemens panelboards and load centers, simplifying replacements and upgrades.
• Versatile for multiple sectors suitable for residential, commercial, and light industrial applications where reliable overcurrent protection is critical.
