Siemens BQ1B01500S01 - 15 A, 120 V, 1-Pole Bolt-On Circuit Breaker | AmpState

The Siemens BQ1B01500S01 delivers reliable protection for your electrical distribution system. This 15A, 120V, 1-pole bolt-on molded case circuit breaker is built to interrupt fault currents quickly, safeguarding panelboards, loadcenters, and connected wiring from damage caused by overcurrent and short circuits.

Key advantages

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that maintains stable electrical contact in panelboards and loadcenters.
• Thermal-magnetic trip unit delivers stable, repeatable protection performance, reacting appropriately to both overloads and short circuits.
• 1-pole, 15A, 120V design is tailored for common branch circuits in residential, commercial, and light-industrial applications.
• OEM-compatible ensures seamless integration with matching Siemens loadcenters and panelboards, helping you maintain a coordinated protection system.
• Purpose-built protection provides dependable branch-circuit overcurrent and short-circuit protection, reducing the risk of wiring damage and electrical fires.

Ideal use scenarios

• Replacing a failed or aging breaker in existing Siemens panelboards or loadcenters without changing the entire distribution system.
• Assigning or upgrading a dedicated 15A circuit for lighting, outlets, or small equipment in residential settings.
• Implementing reliable protection for light commercial or small industrial circuits where consistent trip performance matters.
• Integrating into new installations that require a known, compatible 1-pole, 15A, 120V bolt-on breaker from Siemens.

Compatibility and installation considerations

• Designed for bolt-on mounting to align with compatible Siemens OEM panelboards and loadcenters.
• Part number BQ1B01500S01 confirms the 1-pole, 15A, 120V configuration and thermal-magnetic trip characteristics.
• Ensure the panelboard accepts bolt-on molded case circuit breakers of this type and follow proper torque specifications for secure mounting.
• Best installed by a qualified electrician, with power shut off and system de-energized during replacement or installation.
