Descriere

The KS47 and KSV47 serve for obtaining information on status of VA47-29 and VA47-100 circuit breakers in process automation systems or protection of individual facilities. KS47 has function of auxiliary contact of the circuit breaker or RCCB. The KS47 contacts are switched over even when breaker control lever is held in ON position. KSV47 has function of auxiliary contact and position indication for the circuit breaker or RCCB resetting mechanism. When KSV47 module is engaged with the mechanism of the circuit breaker (VA) or RCCB (AD), at first switching ON the contacts are switched over. KSV47 contacts remain in closed (open) state also when VA or AD devices are switched OFF manually. The contacts will be switched over only when the breaker trips because of overcurrent (caused by overload or short-circuit). A pad is provided in the module upper part, pushing on which causes forced mechanism resetting and contacts switchover. Attached without screws to VA47-29, VA47-100 circuit breakers. Nominal voltage AC 50 Hz: 230 Number of contacts as normally open contact: 1 Number of contacts as normally closed contact: 1 Nominal voltage DC: 110 Max.
