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 1 systems. 8340-T... single pole three pole Standard current ratings and typical internal resistance values Technical data Current Internal resistance values () per pole For further details please see chapter: Technical Information rating (A) F1 F2 K1, M1, T1 K2, M2, T2 Voltage rating 3 AC 415V AC 240V (50/60Hz) DC 80V 0,02 1 493 953 2 669 2 457 (higher DC voltages to special order) Current rating range 0.02...50 A DC 0,05 276 152 452 376 0.02...30 A AC 0,1 58 37 100 94 Auxiliary circuit 1 A, AC 240 V/DC 65 V 0.5 A DC 80 V 0,25 8,2 6,0 15,5 14,7 Typical life 3 AC 415 V AC 240 V: 0.02...30 A 6,000 operations at 1 x I , inductive N 0,5 2,3 1,47 3,9 3,2 10,000 operations at 1 x I , resistive N WDC 80 V: 0.02...25 A 6,000 operations at 1 x I , inductive 0,75 0,98 0,63 1,65 1,56 N 0.02...30 A 10,000 operations at 1 x I , resistive N 1 0,58 0,35 0,95 0,90 40 + 50 A 6,000 operations at 1 x I , resistive N Ambient temperature -40...+85 C (-40...+185 F) 2 0,145 0,096 0,26 0,20 Insulation co-ordination rated impulse pollution 2,5 0,096 0,061 0,15 0,15 (IEC 60664 and 60664A) withstand voltage degree 2.5 kV 2 3 0,065 0,048 0,10 0,10 reinforced insulation in operating area 5 0,025 < 0,02 0,042 0,040 Dielectric strength 6 < 0,02 < 0,02 0,029 0,028 (IEC 60664 and 60664A) operating area test voltage AC 3,000 V 8 < 0,02 < 0,02 < 0,02 < 0,02 Line to Load test voltage AC 1,500 V pole to pole (2- and 3-pole) test voltage AC 1,500 V 10 < 0,02 < 0,02 < 0,02 < 0,02 main to auxiliary circuit test voltage AC 1,500 V 12 < 0,02 < 0,02 < 0,02 < 0,02 Insulation resistance > 100 M (DC 500 V) 15 < 0,02 < 0,02 < 0,02 < 0,02 Interrupting capacity 6 x IN at AC IEC 60934 - test sequence E 4 x IN at DC 16 < 0,02 < 0,02 < 0,02 < 0,02 Interrupting capacity I 0.02...20 A 25...30 A N 20 < 0,02 < 0,02 < 0,02 < 0,02 (UL 1077) AC: 1-pole AC 250 V/3,500A AC 250 V/3,500A 2-pole AC 250 V/3,500A AC 250 V/5,000A 25 < 0,02 < 0,02 < 0,02 < 0,02 3-pole 3AC 250V/3,500A 3AC250V/5,000A 30 < 0,02 < 0,02 < 0,02 < 0,02 DC: 1-pole 0.02...50 A DC 80 V/3,500 A 2-pole 0.02...30 A DC 80 V/3500 A 40 < 0,01 - < 0,01 - Degree of protection operating area IP40 50 < 0,01 - < 0,01 - (IEC 60529/DIN 40050) terminal area IP20 Vibration with toggle down: 10 g at 0.9 I N directions 1, 2, 3, 4, 5: 10 g at 1 x I N with curves F1, F2: 10 g at 0.8 x I in all planes.
