GNW8 series smart intelligent universal Air Circuit Breakers with drawer or fixed type
APPLICATION
GNW8 series intelligent air circuit breaker is applicable for distribution network of AC50Hz,rated voltage of 400V and 690V and rated current 400-6300A to distribute electric energy protection circuit and prevent power equipments from harm of overload ,under voltage ,short circuit and single-phase earth etc. provided with intelligent protecting function and precise selective protection, breaker can enhance the dependability of power supply and avoid unwanted power cut.Standard: IEC 60947-2.
MOMEL IMPLICATION AND TYPE
A: L type(communication available) M type (ordinary intelligent) Ltype( economical);
B: with over load long time delay inverse time limit, short time delay inverse time limit,definite time-lag,instantaneous function. The protection functions can be set by user;
C: single-phase earth protection function;
D:display function:current set display,breaking current display,voltage display(should be advised when ordering);
E:alarming function:with over load alarming;
F:self-check:over heart sel-check,microcomputer self-diagnose check;
G:test function:test the breaking function of controller;
