Breaking capacity, sometimes referred to as interrupting capacity, is the maximum number of amps or volts that a circuit breaker can interrupt. Each apparatus designed to interrupt electrical current can have more than one breaking capacity because the voltage it is exposed to affects the number of amps it can interrupt. It is important to use a breaker that has a high enough breaking capacity to interrupt the maximum possible current and voltage in a system because an unchecked surge in electrical energy can do damage to electronics or to a building.
