SD, SE, SDE, SCO series
Multipole switchgear for voltages up 600 V to 3 kV
Switchgear for rolling stock
The switches of series SD, SE, SDE and SCO have a modular design and can be used for the function disconnect, earthing, disconnect and earthing as well as switching between two circuits (change-over).
The SCO2, SCO3 and SCO4 HV changeover units come in series of 2, 3, and 4 position assemblies. They are manually operated or driven by a linear or geared motor. Multipole and of modular design, they sport up to 10 rotating switching chambers fitted with 8 contacts and one or two knives each.
The rotary scissor switches are designed for off-load adjustment of electrical configurations, especially of multi-system locomotives, but also as reliable HV disconnectors for the power converters and traction motors of electric railway vehicles.
Features
- Off-load adjustment of electrical configurations to different networks, e.g. various train line voltages in accordance with UIC 550
- Suitable for all UIC voltages up to 5 kV DC max.
- Inexpensive high-voltage switch for applications requiring high conventional thermal currents
- Various control programmes available in accordance with the
requirements of the European railway companies - Simple adaptation of control programme to new requirements
