Magnetic and Hydraulic-Magnetic Circuit Breaker 8340-T... www.e-t-a.de 1708 1 1 Description Typical applications Technical data 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). Power supplies, control equipment, communication systems, EDP systems. 8340-T... single pole three pole For further details please see chapter: Technical Information Voltage rating 3 AC 415V; AC 240V (50/60Hz); DC 80V (higher DC voltages to special order) Current rating range 0.02...50 A DC 0.02...30 A AC Auxiliary circuit 1 A, AC 240 V/DC 65 V; 0.5 A DC 80 V Typical life 3 AC 415 V AC 240 V: 0.02...30 A 6,000 operations at 1 x I N , inductive 10,000 operations at 1 x I N , resistive WDC 80 V: 0.02...25 A 6,000 operations at 1 x I N , inductive 0.02...30 A 10,000 operations at 1 x I N , resistive 40 + 50 A 6,000 operations at 1 x I N , resistive Ambient temperature -40...+85 °C (-40...+185 °F) Insulation co-ordination rated impulse pollution (IEC 60664 and 60664A) withstand voltage degree 2.5 kV 2 reinforced insulation in operating area Dielectric strength (IEC 60664 and 60664A) operating area test voltage AC 3,000 V Line to Load test voltage AC 1,500 V pole to pole (2- and 3-pole) test voltage AC 1,500 V main to auxiliary circuit test voltage AC 1,500 V Insulation resistance > 100 MΩ (DC 500 V) Interrupting capacity 6 x IN at AC; IEC 60934 - test sequence E 4 x IN at DC Interrupting capacity I N 0.02...20 A 25...30 A (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 3-pole 3AC 250V/3,500A 3AC250V/5,000A DC: 1-pole 0.02...50 A DC 80 V/3,500 A 2-pole 0.02...30 A DC 80 V/3500 A Degree of protection operating area IP40 (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 N in all planes.
