Typical applications

Technical data

Single and multipole magnetic circuit breakers with trip-free mechanism

and toggle actuation. A choice of fast magnetic or hydraulically dela-

yed switching characteristics (S-type MO or HM CBE to EN 60934)

ensures suitability for a wide range of applications. Industry standard

dimensions and panel mounting. Options include auxiliary changeover

contacts. Low temperature sensitivity at rated load.

Approved to CBE standard EN 60934 (IEC 60934): S-type HM CBE.

Communications systems, power supplies, switchgear and controlgear

industrial process measurement and control.
