Intrerupator general MCCB VA88-40 3P 500A 35kA

VA88 circuit breakers 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.

Easy independent installation of auxiliary devices: – signal contact; – auxiliary contact; – undervoltage trip; – shunt trip; – rotary handle; – motor control; – plug-in panel; – pull-out panel. Standard set of each circuit breaker consists of connecting busbars or cable lugs (depending on the size), phase separators, a set of screws and nuts for its mounting onto an installation panel.
