ABB IEC outdoor AC railways vacuum circuit breaker FSK II+ — outdoor vacuum circuit breaker

Description

The ABB FSK II+ IEC Outdoor AC Railways Vacuum Circuit Breaker is designed for railway power supply, offering single or two-phase operation with a magnetic actuator, rated up to 27.5 kV, 2500 A, and 25 kA or 31.5 kA interrupting capacity. Building on the success of the FSK II over the past decade, it leverages environmentally friendly N2 (nitrogen) gas, a reduced footprint, and the VE1 single vacuum interrupter, while incorporating innovations like externally bolted HV terminals and polymeric insulators. It is electromechanically compatible, providing high flexibility and reliability to meet individual requirements.
