1 / 4 page High Performance Thermal Circuit Breaker 483-... www.e-t-a.de 1646 1 1 Description Typical applications Technical data Single pole, miniaturised, aircraft style thermal circuit breaker with tease-free, trip-free, snap action mechanism and push/pull on/off manual actuation (M-type TO CBE to EN 60934). An indicator band on the push button clearly shows the tripped/off position. Threadneck panel mounted, available in metric and US (MS 3320) configurations. Advanced two-chamber design contributes to fail-safe operation. Temperature compensated from -55 °C to +125 °C, with optional auxiliary contacts, and fully approved for use on a wide range of aircraft and equipment. Full specification ensures suitability for the most demanding applications. For three pole version see type 583. Aircraft systems and equipment (fixed wing and helicopters); other extra low voltage wiring applications; defence equipment; communications systems. 483-... without auxiliary contact with auxiliary contact Voltage rating AC 115 V (300 Hz to 800 Hz); DC 28 V (higher voltage ratings upon request) Current rating range 1...35 A Auxiliary circuit 0.5 A, DC 28 V Typical life 20,000 operations mechanical or 10,000 operations at IN (≤ 25 A) 5,000 operations at IN (30 + 35 A) Ambient temperature -55...+125 °C (-67...+257 °F) Insulation co-ordination rated impulse pollution (IEC 60664 and 60664A) withstand voltage degree 1.5 kV 3 Dielectric strength (IEC 60664 and 60664A) test voltage operating area AC 1,500 V main to aux. circuit AC 1,500 V Insulation resistance > 100 MΩ (DC 500 V) Interrupting capacity Icn AC 115 V (400 Hz): 5 A 2,000 A 7.5...35 A 2,500 A DC 28 V: 1...25 A 6,000 A 30 + 35 A 4,000 A Degree of protection operating area IP40 (IEC 60529/DIN 40050) terminal area IP00 Vibration (sinusoidal) 15 g (70-2000 Hz), ± 0.76 mm (5-70 Hz) to VG 95210, sheet 19, IEC 60068-2-6, test Fc/ISO 7137 Vibration (random) 16.4 g rms, 0.2 g2/Hz ± 1.5 dB to VG 95210, sheet 29, ISO 7137 Acceleration 17 g, to ISO 2669 Shock 75 g (11 ms) to VG 95210, sheet 28, IEC 60068-2-27, test Ea/ISO 7137 Corrosion 96 hours at 5 % salt mist, severity A 48 hours at 20 % salt mist, severity B to VG 95210, sheet 2, IEC 60068-2-11, test Ka/ISO 7137 Humidity 240 hours at 95 % RH, to VG 95210, sheet 7, IEC 60068-2-3, test C/ISO 7137 Explosion to VG 95210, sheet 10, MIL-STD-202, meth. 109 Altitude ≤ 25,000 m above sea level Mass max. 29 g with auxiliary contact max. 25 g without auxiliary contact Weight reduction through aluminium threadneck: approx. 3 g Approvals Standard current ratings and typical volt drop values Current rating (A) Volt drop (mV) Current rating (A) Volt drop (mV) 1 750 10 190 2 520 15 190 2.5 400 20 200 3 360 25 170 4 350 30 160 5 260 35 150 7.5 230 Authority Standard Rated voltage Current ratings UL UL 1077 AC 250 V DC 75 V 1 A…25 A 1 A…35 A CSA C22.2 No 235 AC 250 V DC 75 V 1 A…25 A 1 A…35 A Bw VG 95345, part 6 AC 115 V, 400 Hz DC 28 V 1 A…25 A 1 A…25 A Bw LN 29886 AC 115 V, 400 Hz DC 28 V 1 A…25 A 1 A…25 A QPL Canada Dep. of National Defence VG 95345, part 6 AC 115 V, 400 Hz DC 28 V 1 A…25 A 1 A…25 A QPL Sweden Defence Material Admin.
