FB3125L - 125Amp Circuit Breaker Description

FB3125L - 125Amp Circuit Breaker

When a circuit breaker reaches the end of its service life, finding the right replacement is about more than matching the amperage. The replacement needs to fit the existing equipment, meet the original electrical ratings, and perform the same protective function. The FB3125L is a 125 Amp, 3-pole FB thermal-magnetic circuit breaker designed as a form, fit, and functional replacement for compatible legacy electrical systems. It provides the electrical characteristics needed to help keep existing distribution equipment operating as intended without changing the original design.
