This device is adopted high-powered 32 bits DSP, Chinesization liquid

-crystal display, detailed and visual information, convenience for

operation. The protection device can work safely for long time under

-25C-+55C. KR-1110 is multifunction relay that have all functions,

protection, control and monitoring and remote signalling.communicationintroduces in RS-485 bus network that is economic and

convenient.Various services for breaker operation circuit , operation

compatible between DC and AC voltage, is suitable for all kinds of

breaker control. This device is adopted high-standarded

case,flashboard on the back, no back board binding wire that

guarantees quality plenty on the technique.KR-110 is mainly suitable for line-transformer groups of 6KV and 10KV

voltage, protection for inner failure in synchronous and asynchronous

motor, overload protection.
