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.
