Siemens B130 - 30 A, 120 V, 1-Pole Bolt-On Circuit Breaker | AmpState

The Siemens B130 is a 30A, 120V, 1-pole bolt-on molded case circuit breaker designed to deliver dependable branch-circuit overcurrent and short-circuit protection in panelboards and load centers. Built for reliable performance, it integrates seamlessly with existing Siemens installations and upgrades.

Key advantages that matter in the real world

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that stays seated under heavy or dynamic electrical loads.
• Thermal-magnetic trip unit offers stable, repeatable protection: the thermal element handles gradual overloads, while the magnetic trigger responds quickly to short circuits, helping protect wiring and connected devices.
• OEM-compatible design is matched to corresponding Siemens load centers and panelboards, ensuring proper fit, predictable trip characteristics, and straightforward replacements.
• 1-pole, 30A, 120V configuration is ideal for protecting individual 120V branch circuits—such as lighting, receptacles, or dedicated small equipment lines—in residential, commercial, and light-industrial settings.
• Bolt-on molded case construction combines rugged insulation with reliable electrical performance, suited to installations where panel integrity and long service life matter.

Who benefits from the Siemens B130? technicians upgrading or repairing panelboards, electricians wiring new 120V circuits, and facilities managers maintaining small-to-medium electrical systems. If you’re working with Siemens panel centers, this breaker aligns with the same engineering standards, reducing compatibility concerns and simplifying stocking decisions.
