Magnetic and Hydraulic-Magnetic Circuit Breaker 8340-F... Description Single and multipole 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. 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). Typical application Control equipment, communications systems, transportation, power supplies.
