cutting off or isolating an electrical circuit
Electrical devices need an electrical circuit.
Any devices that are added to a circuit and need the full line voltage to operate, are added in parallel to any other load devices or fixtures in the circuit.
The devices contained in a circuit breaker consist of a bi metal strip for over load protection and a small wrap of wire in the form of a coil for magnetic short circuit trip.

A series circuit is one in which the current must pass through all the electrical devices in the circuit in turn. A parallel circuit is one in which the current passes through each electrical device on the circuit following separate, independent path from all other devices on the circuit, one for each electrical device.
It is usually classed as a device that will open the circuit if the current in the circuit goes high. Two examples of these types of devices are fuses and circuit breakers.
