Earth fault circuit breaker type B, 40A, 30mA 1-phase (4pol)
CE-marked Earth fault circuit breaker for charging station for electric cars, electric hybrids, charging hybrids. Ground fault circuit interrupter of TYPE B has been a requirement since 2017 for charging electric cars. We offer the right switch at an unbeatable price.
For electric car charging and solar installations, you must have a ground fault circuit interrupter type B according to the new electrical installation rules 2017 (Edition 3 of SS 436 40 00). It is a Swedish standard that should be followed. The reason for this is that an ordinary earth fault circuit breaker can stop working if it is used in these contexts, which in the worst case can lead to fire or electrical accidents.
MORE ABOUT THE RULES
How can it be that there is never any talk of earth fault circuit breakers type B for single-phase wall sockets such as charging hybrids are being charged off?
ANSWER: The new rules from 2017 apply to all new installations, a three-phase charging station is in principle always a new installation and these must then either be equipped with earth fault circuit breakers type B or supplemented with one. previously and the requirements do not apply to these. Our opinion is, however, that there is the same risk of electrical accident, fire or damage to electronic equipment in the property where the outlet is located. Based on this reasoning, it is never wrong to supplement an old socket with a single-phase earth fault circuit breaker type B. We also recommend that you replace old wall sockets with new ones of good quality as old wall sockets can cause loose contact and hot running if they are heavily loaded for a long time.
