Are thermal magnetic trip units suitable for AC circuit breakers?
The thermal magnetic trip units fitted to AC circuit breakers are also suitable for use with direct current. The tripping characteristics of the thermal protection do not change since the bimetal strips of the trip units are influenced by the heating caused by current flow. It does not matter whether alternating or direct.
What does a circuit breaker do?
teristics and on the overcurrent value.The circuit breaker is a mechanical switching device, capable of making, car-rying, and breaking current under normal circuit conditions and also, making and carrying for a specified time and breaking current under specified abnormal circuit co
How to choose a circuit breaker?
When choosing a circuit breaker, it is neces-sary to take into consideration the grounding of the plant. This helps define the number of poles to be connected in series with the purpose of creating working conditions under which, if a short-circuit occurs, the current breaking is car-ried out by the series of the four circuit breaker contacts.
What is Ed current in a circuit breaker?

Which circuit breaker is suitable under short-circuit conditions?
According to the column considered, the circuit breaker which would seem suitable under short-circuit conditions is an E2N (N=50kA>Ik). However, according to the table of the rated uninterrupted current (page 39), it is necessary to pass to an E3N since it has Iu= 2000 A which is higher than the current absorbed by the loads.
