Circuit breaker type BA51-25

Three-pole circuit breakers
type VA 51-25 are intended for carrying
current in normal mode in electric
circuits with voltage up to 660V of alternating current
frequency 50, 60Hz and for protection of these
electrical circuits from short-circuit currents
short-circuit and overload currents, and switches
type VA51G25 are designed for starting,
stop and protection of asynchronous
electric motors against overload currents and short-circuit currents
short-circuit currents, as well as for operational switching on and off of the specified circuits.
switching on and switching off of the specified circuits with
frequency of up to 30 switching operations per hour.
