Product Desciption

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

++++General:

     Rockwill Electric strives to bring our customers the latest technology and competitive pricing and best service for distribution automatic.

The RCW series automatic circuit reclosers can use on overhead distribution lines as well as distribution substation applications for all voltage classes 11kV up to 38kV at 50/60HZ power system. and its rated current can reach 1250A.

The RCW series automatic circuit reclosers integrates the functions of control, protection, measurement, communication, fault detection, on-line monitoring of closing or opening.

++++Service environment:
