ABB HD4/R - Gas Insulated MV Circuit Breakers
|HD4/R are used in secondary MV distribution and in MV/LV transformer substations. They are available in fixed version with right-hand side operating mechanism. Circuit-breakers with rated voltage up to 24 kV can be fitted with current sensors and PR521 overcurrent release and can be used in unmanned substations without auxiliary power supply.|
The S200 Series miniature circuit breaker offers a compact solution for protection requirements. The S200 devices are UL tested current limiting and DIN rail mounted.The S200 is available with application-specific trip characteristics to provide maximum circuit protecti
The 145PM-B breaker principally consists of three cast aluminum single-piece tanks, each containing an interrupter unit, mounted on a galvanized steel support structure. Two bushings with removable current transformers mount atop each tank. A steel control cabinet is at
The S800 high performance MCB offers a compact solution to circuit protection. The S800 devices are UL tested current limiting and DIN rail mounted. The S800 is available with application-specific trip characteristics to provide maximum circuit protection. The breakers
The eVD4 circuit-breaker is a complete plug and play medium voltage electrical plant protection system. It is the evolution of the traditional concept of a circuit-breaker and, with a single device, carrying out the breaking, measurement, protection, control and communi
ABB is the first to combine the unique requirements of vacuum interrupter technology with a magnetic actuator designed to exploit these capabilities. Using a flux-shifting device with integral permanent magnets, the R-MAG mechanism has only one moving part. With simple
The 550PM breaker includes three interrupter tanks comprised of cast aluminum and/or steel sections. Each factory completed tank assembly incorporates two (or three) serially connected puffer interrupters, a spring-hydraulic operating mechanism, an enclosure with pre-wi
The circuit breakers for the highest ratings belong to the HPL family of puffer breakers. It is primarily used for applications requiring high rated short-circuit breaking currents above 50 kA. The HPL is ABB's primary offerings for low temperature requirements down to
The GSx II range is the first commercially available single-phase vacuum circuit-breaker intended for the railway power supply and applying a combination of a maintenance-free vacuum interrupter, magnetic actuator and electronic controller.
Vacuum Circuit Breakers OVB-VBF are used in distribution systems ratedat at 24 / 36 / 40.5 kV and are of live tank design. The vacuum interrupters are housed in hollow porcelain insulators filled with SF6/Nitrogen gas at 0.5 bar above atmospheric pressure to safeguard a
The circuit breakers of Tmax series (T1 1P, T1, T2, T3, T4, T5, T6, T7 and T8) are designed complying with the Standards UL 489 and can be applied in installations with currents from 15 to 3000A, with rated voltages of 240V, 277V, 480V, 600Y/347V and 600VAC
