Siemens BG220 Molded Case Circuit Breaker – BG Series – 20A – 2 Pole – 120V – Switching Neutral – 10kAIC – Bolt-On

The Siemens BG220 is a BG Series molded case circuit breaker designed for specialized 120VAC applications requiring switching neutral functionality. This 20A, two-pole breaker disconnects both the hot and neutral conductors during fault conditions, providing enhanced circuit isolation and safety. Featuring thermal magnetic trip technology with Long-Time and Instantaneous (LI) protection, it delivers reliable protection against overloads and short circuits.

The BG220 is designed for bolt-on installation in Siemens panelboards and serves as the direct replacement for the discontinued BG2B020 model, ensuring continued support for legacy electrical systems. Its common trip mechanism and HACR rating make it suitable for a wide range of commercial and industrial applications.
