3. Product Description
3.1. Apparatus
The FSK IIS+ apparatus are designed for outdoor installations and used in 50/60Hz railway traction power supply
networks. They differ in particular by their fast breaking times.
The vacuum circuit-breaker and load break switch types are equipped with a modern magnetically actuated
mechanism instead of the conventional mechanical spring charged mechanism. The main insulators and the
orientation of the HV terminals can be configured according to the customer requirements.
