Safety guaranteed: Functions and advantages of switch-disconnectors

Circuit breakers are used to protect electrical circuits by automatically switching off in the event of an overload or short circuit. They can be switched back on, eliminating the need for one-way fuses. Switch-disconnectors, on the other hand, specialize in safely isolating electrical circuits from the power supply.

Unlike circuit breakers, switch-disconnectors do not perform a protective function, but merely ensure safe isolation as well as prevention of accidental switch-on. Both electromechanical components are indispensable in electrical installations and in the energy sector, with circuit-breakers primarily ensuring the protection of installations, while switch-disconnectors are used for maintenance and repairs.
