What is DP in MCB?
A single pole breaker is used with a typical 120v circuit, having one hot wire and one neutral wire. However, a double pole breaker is used with a typical 220v circuit (like for a dryer or heater) having two hot wires. If there is a short circuit to either hot wire, both poles are ganged together so both trip together.
