A double-pole circuit breaker is an electrical component used to protect circuits and equipment from electrical overloads, short circuits and ground faults. Double-pole circuit breakers automatically interrupt electrical circuits to keep electrical systems operating safely. In a circuit, a double-pole circuit breaker acts like a car fuse. When the current exceeds a certain value, it will open the circuit to avoid overloading and damage to electrical equipment.
