LB3175 - 175Amp Circuit Breaker

LB3175 - 175Amp Circuit Breaker

The LB3175 is a 175-amp, 3-pole Type LB thermal-magnetic circuit breaker with an interchangeable trip unit. The LB3175 measures 5.50 inches wide × 10.13 inches long × 3.94 inches deep, which matters when you need the right form and fit in existing or legacy equipment. When properly matched to the application, installed correctly, and operated within its specified ratings, the LB3175 is built to last in the application it was designed for.
