    IEC outdoor gas insulated (SF6) circuit breaker OHB

    IEC outdoor gas insulated (SF6) circuit breaker OHB


    Medium Voltage circuit breaker with mechanical operating mechanism designed for distribution systems up to 40.5 kV, 2500 A, 31.5 kA.

    These circuit breakers are of live tank design. They are used in power distribution for control and protection of lines and for control and protection of transformers, rectifier units, capacitor banks, etc. Thanks to the autopuffer breaking technique, they do not generate operating overvoltages. This means they are also highly suitable for retrofitting, where the plant insulating materials may be sensitive to dielectric stresses.

    Why ABB?

    § Maintenance-free poles

    § Upper and lower terminals with NEMA4 drilling

    § Gas pressure control device for each pole

    § Poles made with porcelain insulators, assembled by means of flanges with terminals

    § Inspection window in the pole supporting casing near the operating mechanism signals.

    IEC outdoor AC railways vacuum circuit breaker FSK II+

    MV single or two-phase circuit breaker with magnetic actuator designed for railway power supply up to 27.5 kV, 2500 A, 25 kA / 31.5 kA.

    FSK II+ is an evolutionary process that builds on the success established by the FSK II over the past 10 years thanks to key advantages such as the use of environmentally friendly N2 (nitrogen), its reduced footprint and the VE1 single vacuum interrupter, yet it also incorporates some important innovations, such as the externally bolted HV terminals and the polymeric insulators. The FSK II + is electromechanically compatible, as well as offering a high level of flexibility and reliability to meet individual requirements.

    Why ABB?

    § Alternative technologies with low environmental impact

    § Polymeric insulator

    § Same design for single-phase and two-phase configurations

    § On Site configurable High Voltage Terminations orientation

    § Compact footprint
