To handle UIC voltages safely and reliably is the trademark of Schaltbau switchgear such as AC vacuum circuit breakers, disconnecting and earthing devices as well as sensors and controlgear.
Changeover units, for instance, are needed in international mainline service for reconfguring the control circuits of the auxiliaries with the change of catenary voltage after crossing the border. For this purpose Schaltbau has added rotary scissor switches to its product range of controlgear. The two, three and four position changeover switches have an open modular design and are easy to confgure and customize.
