Technical data
Single or multipole hydraulic-magnetic circuit breakers with trip-free -
mechanism and toggle actuation. A choice of switching characteristics
ensures suitability for a wide range of applications. Industry standard
dimensions and panel mounting. Auxiliary contacts optional. Low
temperature sensitivity at rated load.
Approved to CBE standard EN 60934 (IEC 60934) S-type HM CBE.
In the business fields Communication and Transport: power supplies,
switchgear, instrumentation and process control engineering.
