FD3150 - 150Amp Circuit Breaker

FD3150 - 150Amp Circuit Breaker

When your breaker reaches the point where it needs to be replaced, the goal is usually simple: find the right match and get the equipment back into service. The amperage rating is a good starting point, but it is not the only thing that matters. Frame style, trip unit, voltage rating, terminal arrangement, and interrupting capacity all play a role in making sure the replacement fits the application.

The Eaton FD3150 is a 150 Amp, three-pole molded case circuit breaker from the Series C family, built for compatible FD-frame electrical distribution systems. It uses a T186 thermal-magnetic trip unit to respond to overloads and short circuits while meeting the protection requirements of the original equipment. Rated for 600 VAC and 250 VDC, this breaker is designed for 50/60 Hz systems and includes line and load terminals.
