FB2020 - 20Amp Circuit Breaker

FB2020 - 20Amp Circuit Breaker

The FB2020 is a 20 Amp, two-pole thermal magnetic circuit breaker built for use in compatible FB-series electrical distribution equipment. It's most often installed as a replacement breaker when an existing unit with the same ratings needs to be swapped out, allowing the original panel configuration and protection scheme to remain unchanged.

You'll typically find this breaker protecting 240V and 480V branch circuits serving equipment such as HVAC systems, pumps, motors, lighting, or other dedicated loads that require both poles to trip together. Matching the original breaker is especially important in existing installations, and that's where the FB2020 is commonly used.
