LA3300 - 300Amp Circuit Breaker Description
LA3300 - 300Amp Circuit Breaker
The LA3300 is a 300-amp, 3-pole Type LA molded-case circuit breaker for your compatible electrical equipment that requires this specific combination of ratings, size, and configuration. It uses a thermal-magnetic design with an interchangeable trip unit, is rated for 40°C, and includes load-side terminals. When those details agree with the equipment requirements, the LA3300 is a good fit for maintaining compatible existing and legacy electrical systems. Properly selected, professionally installed, and kept within its stated ratings, it's built to last.

Material Compliance and Certifications
No specific material-compliance information or certification details were provided for the LA3300, so do not assume certifications such as UL, RoHS, or REACH.
Where It Works Best
The LA3300 makes the most sense in existing and legacy electrical equipment that specifically requires a 300-amp, 3-pole Type LA thermal magnetic circuit breaker with an interchangeable trip unit.
For replacement work, put the old breaker and the LA3300 specifications side by side. Confirm the part number or Type LA designation, amperage, pole count, system voltage, required A.I.C., dimensions, 40°C rating, trip-unit arrangement, and connection requirements. Load-side terminals are included, but other lug, terminal, and mounting details weren't provided and should be checked separately.
