FD3110L - 110Amp Circuit Breaker

FD3110L - 110Amp Circuit Breaker

When your 110 amp breaker needs to be replaced, the important thing is making sure the replacement belongs in the equipment it is going into. The amp rating is a good place to start, but it is not the whole story. Frame size, trip unit, voltage rating, terminal arrangement, and interrupting capacity all need to match before the breaker is put back into service.

The Eaton FD3110L is a 110 Amp, three-pole molded case circuit breaker from the Series C family with an F-frame design for compatible applications. It uses a T186 thermal magnetic trip unit to respond to overloads and short circuits while following the protection requirements of the original electrical system. Rated for 600 VAC and 250 VDC, this breaker is designed for 50/60 Hz systems and includes line and load terminals.
