    Circuit BreakersContactorsMotor StartersDisconnectors, Load-Break Switches and Switch DisconnectorsFusesCircuit-breakers are defined in IEC 60947-2. Circuit-breakers most be capable of making, conducting and switching off currents under operational conditions. Furthermore, they must trip in accordance with defined current/time characteristics under overload and short-circuit conditions. Circuit-breakers are used in applications with a low switching frequency. Circuit-breakers without overcurrent releases are known as switch-disconnectors. The basic classification criteria for low voltage circuit-breakers are the design (compact or open) and the quenching principle (non-current limiting or current limiting). Non-current limiting circuit-breakers quench the switching arc at the natural alternating current zero. The conductors are designed with a thermal capability allowing them to conduct the full short-circuit current. All system components downstreamare also subjected thermally and dynamically to the unlimited peak short-circuit current. Current limiting circuit-breakers limit the sho...
