Magnetic and Hydraulic-Magnetic Circuit Breaker 8335-...
Description
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.
Typical applications
Communications systems, power supplies, switchgear and controlgear
industrial process measurement and control.
