The innovative modular system is both simple and very safe while offering enormous flexibility.

The core component, the rotary contact system incorporated in a new type of modular contact block
allows high mechanical life expectancy and precise and reliable contact making.

Visible contacts (with an additional window) can be made available on request

The position of the latching mechanism is more or less unlimited.
The design allows for future expansion of the line with different terminal or contact technology like
cage clamps, or knife contacts for DC applications.

The same modules can be used for panel mounting,
lateral drive and base mounting, minimizing the need for high inventory levels and saving money.

1-6 pole On-Off switches (later also 7-9 pole On-Off switches and 1-4 pole Change-over switches)
are delivered as preassembled units from the factory.
4^th poles as well as the precisely working cam-operated auxiliary contacts can be added in the field.

Coupling profile determines pre-closing function of switched 4th pole,
    i.e. contact modules per se are always the same

Rotating contact movement (instead of classical vertical lifting) allows

    big contact gaps
    high mechanical life expectancy
    very precise movement sequence
    self-cleaning contacts
    forced opening and closing of contacts

Compact (very shallow) design

Up to 1000V insulation voltage according to IEC possible

Lateral drive possible (latching module not in the centre but on left or right hand side)

Visible contacts (windows) available on request

Design allows a big variation of terminal markings

Removal from DIN rail can be done without tool change (screw driver for cross-recessed
    screws sufficient)
