LA3400PR - 400Amp Circuit Breaker

LA3400PR - 400Amp Circuit Breaker

The LA3400PR is a reliable 400-amp, 3-pole Type LA fusible circuit breaker built on the LA3400PRF frame. When replacing an old breaker, check the part number, frame type, pole configuration, amperage, voltage, interrupting ratings, and dimensions. If these details match, the LA3400PR will fit seamlessly into your setup.
