Therefore the suitable circuit breaker is a three-pole E3N 2000 circuit breaker with PR1122-123/DC In=2000 A. The connection of the poles is carried out in the factory by ABB. The solution of the table shows the connections between three-pole circuit breaker, load and supply source.
Miniature circuit breakers available for use in direct current are series S280UC, S800S UC and S800 PV. Miniature circuit breakers series S280 UC comply with IEC 60947-2 and differ from the standard versions in that they are equipped with permanent magnetic elements on the internal arcing chambers.
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.
Circuit breakers, devices carrying out the protection func-tion against overcurrents, are divided into three families including miniature circuit breakers, molded case circuit breakers and air circuit breakers. Miniature circuit breakers available for use in direct current are series S280UC, S800S UC and S800 PV.
When used for DC applications, they are available for rated current from 15 A (T1) up to 800 A (T6). For applications where higher currents are required, it is possible to connect the circuit breaker poles in parallel so that the required current carrying capacity can be obtained.
For Emax circuit breakers, please ask ABB. With this network type, the poles connected on the terminal insulated from ground are called to break a fault current at 1000 V; therefore it is necessary to provide on this terminal the series of four poles.
