Item: RCW38M  RCW38N

RCW38M RCW38N type pole mounted circuit recloser

RCW38M (RCW38N) is patented type recloser by Ezitown .Which has innovation design for magnetic actuator and addtional manual closing for prevent defect of auxiliary power outage moreove the circuit breaker in opening situation case.

RCW38M (RCW38N)  series recloser is very relieable products, suitable for important position performance.

The main difference between RCW38M and RCW38N:

 Type Close energy Open energy Mechanical life
 RCW38M By capacitor charging, fast within 1 S Need By capacitor  release More than 60,000  times
 RCW38N By motor charging spring, long        time 7S~15S No need capacitor 10,000 times
