WL/r 12÷24kV

WL-r series withdrawable vacuum circuit breakers are suitable for metal-clad type SYSclad switchboards. They are realized using the separate pole technique.

Each pole has a vacuum interrupter inside which, thanks to a special production process, is built in the resin directly during the cylinder moulding stage.

This construction technique ensure protection of the vacuum interrupter against impact, dust and condensation.

The operating mechanism is stored energy type and free unlock system, with opening and closing operations independent from the operator.

The circuit breaker is fitted on a trolley with racking mechanism which permit at the VCB to assume inside the panel the “inserted, sectioned, extracted”.

Mechanical interlocks guarantee maximum safety of the operator.
