LA3150 - 150Amp Circuit Breaker

LA3150 - 150Amp Circuit Breaker

The LA3150 is a 150-amp, 3-pole Type LA thermal-magnetic circuit breaker with an interchangeable trip unit and load-side terminals. If you’re matching a breaker already installed in older equipment, compare the catalog number, amperage, poles, interrupting ratings, trip configuration, dimensions, and terminals rather than going by amperage alone.

Where It Works Best

The LA3150 is best suited to compatible existing or legacy electrical equipment that requires a 150A, 3-pole Type LA thermal magnetic circuit breaker with an interchangeable trip unit.

A good replacement check starts with the catalog number and Type LA designation, but don’t stop there. Confirm the 150A rating, three poles, 40°C rating, and required interrupting capacity. The application should correspond with the LA3150 ratings of 22kA at 600VAC, 30kA at 480VAC, or 42kA at 240VAC, as applicable.
