Equipment for protection and control

The installation stability protection and control device from CIRCUTOR is intended to ensure the safety of users and electrical installations.


The increasing use of semiconductor devices, inverters, computers, and more often generate power distortions that can cause installation outages. This requires the use of protection systems that can distinguish between installation faults and installation changes that can lead to unwanted shutdown of the protection systems.


Residual current protection and control products are divided into several groups. These are, for example, programmable relays for monitoring leakage current, as well as relays in combination with a circuit breaker in one module and, last but not least, also in combination with an element of wet restoration of function after switching off the protection system.
