Replacing the SH630 / M circuit breaker with a new Tmax T5 circuit breaker by ABB 

Circuit breaker Tmax T5 with PR221DS electronic protection by ABB has obtained a positive opinion for use in flameproof transformer stations. In the overhauled or serviced transformer stations, the lower voltage chamber of the substation was equipped with the ABB Tmax T5 circuit breaker, instead of the previously used SH630 / M circuit breaker. The station’s flameproof enclosure and other electrical equipment remained unchanged.

After installing a Tmax T5 circuit breaker with PR221DS electronic protection in transformer stations in accordance with DT by an employee of IZOL-PLAST, the level of
explosion safety of flameproof transformer stations and stations retain the previous approval feature.
