Features:
1) Working as feeder protection switches, they are especially applicable to
metro subway stations f and light rail vehicle traction systems
2) They can also be used as protection switches for rectifier devices and DC
motors in heavy industries (e.g. steel rolling, mining)
3) Breakers are mainly used as short-circuit and overload protection
4) Rated voltage DC1500V (and below)
5) Rated current up to 4000A
6) Used for short-circuit and overload protection in rectifier units, DC motors
and feeder circuits
