LA3350 - 350Amp Circuit Breaker

LA3350 - 350Amp Circuit Breaker

The LA3350 is a 350-amp, 3-pole Type LA molded-case circuit breaker with a thermal-magnetic design and an interchangeable trip unit. If you're working with existing or legacy equipment, compare the Type LA designation, 350A rating, three-pole configuration, voltage and interrupting capacity, trip-unit arrangement, dimensions, and connections with the breaker being replaced. When those details match the equipment requirements, the LA3350 provides the form, fit, and function needed to keep the application in service.

Where It Works Best

The LA3350 is best suited for existing and legacy electrical equipment that requires a 350A, 3-pole Type LA thermal magnetic circuit breaker with an interchangeable trip unit.

For a replacement application, compare the existing breaker's specifications with those of the LA3350. Check the Type LA designation, 350A rating, three-pole configuration, system voltage, required A.I.C., 40°C rating, dimensions, trip-unit arrangement, and terminal requirements. Load-side terminals are included; other terminal, lug, and mounting details were not provided and should be verified against the equipment.
