The VB4-P-35 U2 circuit breaker with a spring-motor drive is designed for use in indoor and outdoor high-voltage switchgears (KRU), as well as for replacing worn-out switching devices in KRU of previous years of manufacture.
The switch consists of a housing, three poles, built-in spring-motor drive.
PECULIARITIES:
high mechanical resource;
high switching resource;
low power consumption for switching on and off circuits;
the ability to control the operational circuits on direct or alternating current;
the possibility of implementing a mechanical blocking of the switch;
a closed cast pole is used.
