BQ1B02000S01 - 20Amp Circuit Breaker

BQ1B02000S01 - 20Amp Circuit Breaker

When your electrical system requires both dependable circuit protection and remote shutdown capability, the Siemens BQ1B02000S01 provides a practical solution. This 20 amp, 1-pole BQ series circuit breaker is designed to protect branch circuits from overloads and short circuits while incorporating a factory-installed 120VAC shunt trip, making it suitable for applications where authorized control devices need to remotely disconnect power.

Designed for use in compatible Siemens panelboards and electrical distribution equipment, the BQ1B02000S01 features a secure bolt-on connection that helps maintain a solid electrical and mechanical connection. Its 10kAIC interrupting capacity provides fault protection for branch circuits, helping protect conductors and connected equipment from damaging fault conditions. The integrated shunt trip adds remote tripping capability that can be used with emergency stop stations, fire alarm systems, building automation controls, and other approved control systems.

Whether you're replacing an existing breaker, maintaining facility equipment, or working on a project that requires remote breaker operation, the Siemens BQ1B02000S01 provides the required form, fit, and function for compatible Siemens BQ-series installations. Load-side lugs are included to help simplify installation, while the molded case construction is built for long-term use when properly installed and maintained.
