5.4. Withdrawable circuit-breaker
The withdrawable circuit-breakers (see fig. 5) are available for
CBE enclosures, CBF fixed parts, UniVer C switchboards, ZS1
switchboards and UniSafe switchboards. They consist of a
truck on which the supporting structure of the circuit-breaker
itself is fixed. The cord with the connector (plug) for connection
of the operating mechanism electrical accessories comes out
of the front protection of the circuit-breaker.
The strikers for activating the contacts (connected/isolated),
located in the CBE enclosure or in the switchboard, are fixed in
the top part of the circuit-breaker. The slides for activating the
segregation shutters of the medium voltage contacts of the
enclosure or switchboard are fixed on the sides of the circuit-
breaker. The crosspiece for hooking the circuit-breaker for the
connection/isolation operation by means of the special operat-
ing lever is mounted on the front part of the circuit-breaker
truck.
