The new series of air circuit-breakers consists of five sizes (E1, E2, E3, E4 and E6) in the fixed and withdraw able versions, with rated uninterrupted currents from 800 to 6300 A and breaking capacities up to 150 kA at 415 V.

Different models of circuit-breakers for each size are available, all with the same dimensions, but with various rated currents and with different breaking capacities, identified by letters, as specified in the table.

The series is completed by a range of current-limiting circuit-breakers, of different construction concept, particularly recommended in plants characterized by high short-circuit currents.

Customization of the circuit-breaker is carried out by means of a complete range of accessories - common over the whole range, which can be installed from the front of the circuit-breaker without the need for any internal cabling

Field of application:

They are used in all types of plants (civil, industrial, and in the service sector) as well as in the equipment on-board ships, in mines, in prefabricated substations, and for primary and secondary distribution in general.
