The Westinghouse FDB3020L is a 3-pole, 20-amp circuit breaker designed to protect electrical panels by interrupting current during overload or short-circuit conditions. As a 3-pole device, it provides protection for three conductors within a single breaker, a common configuration in panel installations requiring multi-line protection. The model designation FDB3020L identifies the specific breaker within the FDB series and indicates its 20-amp rating. This unit is used to safeguard circuits in electrical panels, helping prevent wiring damage and reduce fire risk by tripping at the set current threshold.
