High Quality RCCB Miniature Circuit Breaker with CeKNL6
series Residual current circuit breaker(without over-current
protection) is suitablefor the line of A and S 50/60Hz, voltage
230V(2pole)/400V(4pole), rated current up to 80A. Whenthere is
human electricity shock or if the leakage current of the line
exceeds the prescribedvalue, it will cut off the power rapidly to
protect human safety and prevent the accident due to the current
leakage. It can be used as infrequent changeover of the line in
normal situation. It is applicable to industrial site, commercial
site, tall building and civil house. It complies with standard of
IEC/EN61008.1 and GB16916.1. Each phase of conductor at the circuit
breaker passes through the zero-sequence Current tr ansformer, and
the secondary side of coil connects with the electromagnetic
tripper. Under normal condition, the vector sum of each phase of
current passing through zerosequence current transformer is zero.
The flux of the zero-sequence current transformer is zero. And the
secondary output voltage is zero and the circuit breaker doesn t
zero, and the zero-sequence current transformer would produce the
magnetic flux, and the secondary side of coil would output the
voltage. Once the leak current increases to drive the output
voltage at the secondary side to grow to certain level, the
electromagnetic release would activate to drive the operation
mechanism to act to break the contact that connects the power,
finally to realize the leak protection. Frame63ARated working

Ltd, It is a joint venture. My company is a manufacturer including
design, development, produce and sale, professional producing MCB,
MCCB, RCCB and AC contactor etc. Product enterprises. The company
owns import and export power of self-run, expanding Europe and
America, Middle East, Southeast Asia etc. Market, set a good Public
praise. The company have more than 1500 workers, including senior
engineer among them, engineer at inside of more than 100
technician. And then set up to cover area more than 50 acres,
construct area is more than 38000 square meters of the modern
industrial zone, providing with the forerunner's standard
laboratory and various examination equipments. Under Korlen people
to make great effort unremittingly, designed and developed by
oneself, develop and produce the series of MCB, RCCB filled up
local blank, attain inter-national advanced level, and acquire more
than 20 national patents. The company acquires "30 strong eminent
enterprises, top ten of export income, yueqing star class
enterprise, attach importance to contract and keeps promise" title
of honor for many times past years. Company still the initiative
pass ISO 9001 management system verification and 14001 environments
management system verification. Our product passed quality
verification of domestic and international authority organization
like the CB SEMKO NF SIRIM SNI CE PCT TSE, In the meantime high
breaking capacity breaker of our company in this city is the unique
product which got " Yueqing famous brand product" by Yueqing people
government. Korlen Electric Appliances is willing to make friends
with social public, the world outside businessman join hands
together for prosperous society and development to build a brighter
future.CertificatesFactory LinesExhibition /* January 22,
