Ex9L-N residual current circuit breakers are suitable mainly for domestic applications. They are based on electromagnetic principle. It brings the advantage of Voltage independent function. Adequate voltage is only necessary when testing the RCCB with the T test button. Magnetic RCCBs should be tested regularly with a period of one month. 6 kA variant of the Ex9L-N residual current circuit breaker is intended mainly for low demanding application like basic protection in household installations.
