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
1
Power supplies, control equipment, communication systems,
EDP systems.
