FB2040 - 40Amp Circuit Breaker

FB2040 - 40Amp Circuit Breaker

When a circuit breaker reaches the end of its service life, finding a replacement that matches the original electrical ratings is essential. The FB2040 is a 40 Amp, 2-pole FB thermal-magnetic circuit breaker built for that purpose. It helps protect electrical systems from overloads and short circuits while maintaining the original form, fit, and function of compatible equipment.

You'll commonly find breakers like the FB2040 protecting lighting panels, HVAC equipment, pumps, machinery, and general power distribution circuits in commercial buildings, manufacturing facilities, schools, healthcare facilities, and similar environments.
