BG220 - 20Amp Circuit Breaker

BG220 - 20Amp Circuit Breaker

The Siemens BG220 is a 20 amp, 2-pole circuit breaker designed for 120V electrical distribution applications that require a switching neutral configuration. It features a thermal-magnetic trip mechanism to help protect your circuits from overloads and short circuits while providing simultaneous switching of both the line and neutral conductors.

With a 10kAIC interrupting rating and bolt-on mounting design, the BG220 is intended for use in compatible Siemens panelboards. It is commonly installed in applications where switching the neutral conductor is required as part of the circuit design. For maintenance and replacement projects, matching the original breaker specifications—including amperage, voltage rating, pole configuration, and connection type—is often critical, and the BG220 is designed to meet those requirements.

The BG220 is used across a range of commercial, institutional, and specialty electrical installations where maintaining system compatibility and proper circuit protection is important.
