Magnetic and Hydraulic-Magnetic Circuit Breaker 8345-...
Description
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.
Typical applications
In the business fields Communication and Transport: power supplies,
switchgear, instrumentation and process control engineering.
