Where It Works Best
The LA3400 makes the most sense in existing and legacy electrical systems that call for a 400-amp, 3-pole Type LA thermal magnetic circuit breaker with an interchangeable trip unit.
Before choosing it as a replacement, put the specifications side by side with the existing breaker. Check the LA3400 part number or Type LA designation, amperage, number of poles, system voltage, required interrupting rating, 40°C rating, trip-unit configuration, and physical dimensions.
