Описание
Moulded case circuit breakers (MCCB) VA88 are intended for conducting current in normal mode and switching it off at short circuits, overload, inadmissible bucking as well as operational actuation and tripping of electric circuit parts. They are designed for use in electric units having the operative voltage limited to 400 V per rated current from 12,5 to 1600 A. Correspond to the requirements of EN 60947-1, EN 60947-2.
