In addition to ABB, the French company GEC-ALSTOM, Japan's Mitsubishi and other companies have also developed a SF6 generator circuit breakers. GEC-ALSTOM company manufacturing generators long history, although it also produces SF6 generator circuit breakers, but it is known for the production of air generator breaker. It produces SF6 generator circuit breakers development more slowly, but capacity is small. Maximum air generator breaker parameters are: rated voltage of 36kV, rated current is 37500A, breaking current 275kA. Air GCB is the use of compressed air as an insulating and arc extinguishing medium and the cooling medium and the operating gas circuit breaker. Although air generator breaker is a series of strong, highly versatile product, but its large dimensions, covering more expensive, and the need to set up additional compressed air system. Japan's Mitsubishi Corporation in 1977 and began production of the generator circuit breaker uses SF6 gas insulated medium is a maximum breaking current of 110kA, breaking times 10 times; breaking breaking times rated current 42000A is 50 times. Currently breaking current of the generator breaker 125kA being manufactured.

In addition to SF6 gas and air as the insulating medium SF6 generator circuit breakers and air GCB, the late 1980s and early 1990s and developed the use of vacuum technology vacuum generator circuit breakers, the generator circuit breaker is developed and manufactured by the German company Siemens. 8BK40,8BK41 series that is produced by Siemens vacuum generator circuit breakers, the rated voltage of 7.2 ~ 17.5kV, which 8BK40 rated current 5000A, maximum breaking current of 63kA;? 8BK41 rated current of 4000 ~ 12000A, the largest open breaking current of 80kA. Vacuum generator breaker since breaking level is limited, is greater than the vacuum circuit breaker breaking current 63kA have been very difficult to manufacture, but the price is more expensive, so the current vacuum generator circuit breakers using relatively small capacity generator unit more use of large units is limited.Perkins 1103A-33TG1 Perkins 1103A-33TG2 Perkins 1104A-44TG2 Perkins 1104C-44TAG2 Perkins 1006TAG Perkins 1006TAG2 Perkins 1106A-70TAG3 Perkins 1106A-70TAG4 Perkins 1306C-E87TAG3 Perkins 1306C-E87TAG4 Perkins 1306C-E87TAG6 Perkins 1606A-E93TAG4 Perkins 1606A-E93TAG5 Perkins 2206A-E13TAG2 Perkins 2206A-E13TAG3 Perkins 2506A-E15TAG1 Perkins 2506A-E15TAG2 Perkins 2806C-E18TAG1A Perkins 2806A-E18TAG2 Perkins 4006-23TAG2A Perkins 4006-23TAG3A Perkins 4008TAG1A Perkins 4008TAG2A Perkins 4012-46TWG2A Perkins 4012-46TWG3A Perkins 4012-46TAG2A Perkins 4012-46TAG3A Perkins 4016TAG1A Perkins 4016TAG2A Perkins 4016-61TRG3
