Magnetic and Hydraulic-Magnetic Circuit Breaker 8350-... Description Single, two, three and four pole magnetic and hydraulic-magnetic circuit breakers with trip-free-mechanism and toggle or rocker 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. Low temperature sensitivity at rated load. Approved to CBE standard EN 60934 (IEC 60934). Typical applications Communications systems, process control and transportation. 8350 Standard current ratings and typical internal resistance values Technical data Current rating (A) Internal resistance () per pole Voltage rating 3 AC 415 V AC 240 V 50/60 Hz DC 80 V 11.1 Current rating range 0.1...70 A multi pole 3 5 0.034 0.1...100 A single and double pole 10 < 0.02 Auxiliary circuit 6 A, AC 240 V / DC 28 V 15 < 0.02 1 A, DC 65 V 20 < 0.02 0.5 A, DC 80 V 25 < 0.02 Typical life 10,000 operations at I N 30 < 0.02 Ambient temperature -40...+85C (-40...+185 F) 40 < 0.02 Insulation co-ordination rated impulse pollution (IEC 60664 and 60664A) withstand voltage degree 50 < 0.02 2.5 kV 2 60 < 0.02 reinforced insulation in operating area 80 < 0.02 Dielectric strength AC 3750 V 100 < 0.02 Insulation resistance > 100 M (DC 500 V) Degree of protection operating area IP40 (IEC 60529/DIN 40050) terminal area IP00 Vibration 10 g (55-500 Hz) 0,76 mm (10-55Hz) to IEC 60068-2-6, test C 10 frequency cycles/axis per Method 204C, test Condition A.
