HSW1 Series Intelligent Type Air circuit breaker

Description

HSW1 Series intelligent type air circuit breaker with intelligent protective functions and open type communicative interfaces, the breaker has a very accurate selective protection(The industry’s first stepless adjustable technology, have excellent technology of friendly man-machine dialogue ) resulting in elimination of unnecessary down time and four remote performances(Remote sensing, remote adjustment, remote inquiry and remote control) so as to satisfy the requirements from control center and automatic system. And consequently, the reliability of power supply is greatly enhanced. The circuit breaker has a function of isolation, can be derived wind power and other situations in low temperature. All series of products which can be installed into line up and down into the line breaking index, The circuit breaker complies with GB14048.2 and IEC60947-2, has passed China Compulsion Certification (CCC) tests.
