Technical Data
Switching system
The double-break switching system can be supplied for the follo-
wing switching functions: 1 normally closed, 1 normally open or
1 changeover contact with or without overlap.
The normally closed contacts have forced opening according to
DIN 0660, IEC 60947-5-1 and DIN VDE 0113.
The switching element exhibits high reliability due to its H-contact
system with relative friction. The normally open and normally closed
contacts can be used electrically separated.
The standard version is ideal for high breaking capacities. For lower
capacities a special version can be supplied.
