Goal
Ex9L residual current circuit breakers are designed for domestic and industrial use. Their design is based on the classic principle of operation of a permanent magnet and a polarized relay. The advantage of this solution is the independence of the protective functions from voltage. The corresponding voltage value is only required during the periodic testing of the residual current circuit breaker using the “T” button. The residual current circuit breakers should be tested regularly, every month. The 6 kA version of the Ex9L-N residual current circuit breakers is mainly intended for less demanding applications, such as basic protection in domestic installations.
