LD3400 - 400Amp Circuit Breaker Description
LD3400 - 400Amp Circuit Breaker
The LD3400 is a 400-amp, 3-pole Type LD thermal-magnetic circuit breaker with an interchangeable trip unit. For maintenance and replacement work, it gives you several clear specifications to match against the breaker already in service: amperage, pole count, interrupting capacity, dimensions, and trip-unit configuration. When properly selected, installed, and operated within its specified ratings and intended application, it's built to last for the job it was designed to do.

Where It Works Best
The LD3400 makes the most sense when you're maintaining compatible equipment that already calls for a 400A, 3-pole Type LD breaker. This can be especially useful for existing and legacy electrical systems where maintaining the required physical and electrical configuration matters.
