Overcurrent circuit breakers, commonly known as "eska," are components of electrical installations designed to interrupt the continuity of a circuit when the current flowing through it exceeds the safe value for that circuit.
Isolating switches are used as main emergency switches. They protect against the effects of short circuits and overloads. The switches conduct current under nominal conditions and in the event of a short circuit or overload in electrical installations. They ensure safe operation during maintenance and servicing of devices and networks.
Residual current devices (RCDs) are elements of electrical installations designed to protect people and property. They provide fire protection, monitor insulation integrity, and disconnect the power supply when current leakage occurs.
