Magnetic and Hydraulic-Magnetic Circuit Breaker 8340-T...
Description
Single, two and three pole magnetic and hydraulic-magnetic circuit
breakers with trip-free mechanism and toggle actuation. A choice of
fast magnetic only or hydraulically delayed switching characteristics
(S-type MO or HM CBE to EN 60934) ensures suitability for a wide
range of applications. Featuring a combi-foot design for symmetric rail
mounting. Low temperature sensitivity at rated load.
Approved to CBE standard EN 60934 (IEC 60934).
Typical applications
Power supplies, control equipment, communication systems, EDP
systems.
