Product Description

KEMA type tested and certificated products!

The ER series automatic circuit reclosers by shorten as auto recloser which can used 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 ER series auto recloser offers three type smart software for human-computer interaction friendliness application. which functions high efficient and save most cost of time and money expense.

The ER auto recloser offer totally 10curves for user choice as Per standard IEC 62271-111 and IEEC/ANSI C37.60: 5 IEC standard and 5 ANSI standard.
ER series auto recloser also provide with programable software for customized make relay function.

                                         

ER type recloser offer very importance APP management software insert to distribution automation management system.

                                        

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.
