The air switch disconnectors derived from the Emax air breakers are identified

by the standard range code together with the code “/E MS”.

These comply with the international Standard IEC 60947-3 and are especially

suitable for use as bus-ties or principle isolators in direct current installations,

for example in electrical traction applications.

The overall dimensions and the fixing points remain unaltered from those of

standard breakers, and they can be fitted with various terminal kits and all the

accessories for the Emax range; they are available in both withdrawable and

fixed versions, and in three-pole version (up to 750 Vdc) and four-pole (up to

1000 Vdc).

The withdrawable breakers are assembled with special version fixed parts for

applications of 750/1000 Vdc.

The range covers all installation requirements up to 1000 Vdc / 3200 A or up to

750 Vdc / 4000 A.

A breaking capacity equal to the rated short-time withstand current is attributed

to these breakers when they are associated with a suitable external relay
