  • ASCO 7000 SERIES Power Transfer Switches

    2020-11-11In order to meet NEC selective coordination requirements, short-time settings are specified on circuit breakers following a coor-dination study. A circuit breaker’s short-time settings require transfer switches to withstand and close-on short circuit currents for time durations of 0.1 seconds (6 cycles for a 60Hz system) or longer.

  • SF6 Circuit Breakers - Construction, Types and Working

    2021-2-24The sulphur hexafluoride gas (SF6) circuit breaker gives noiseless operation due it’s closed gas circuit and no exhaust to atmosphere, unlike the air blast circuit breaker. The compact design of SF6 gas CBs substantially reduces space requirements and building installation costs. The SF6 gas circuit breakers can handle all known switching phenomena.
