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.
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.
With the help of special buckles VA88-32 and VA88-33 units can be installed onto a DIN-rail.
