RCW38M type pole mounted circuit recloser
RCW38M is patented type recloser by Rockwill ELectric.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 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
