E-T-A 808-H-2A

Magnetic Overcurrent Circuit Breaker 808-... Description Single pole miniaturised magnetic circuit breakers with unique high- speed operating mechanism and push/pull on/off manual actuation. Fitted with electrically separate excitation and switching circuits, and one pair of auxiliary contacts which close when the main circuit is open. Also suitable for impulse operation. Designed for printed circuit board mounting. Low temperature sensitivity. Typical applications Printed circuit boards and components, safety and control systems. 1 808 Ordering information Type No. Technical data 808 fast-acting Manual release H manual release facility Voltage rating DC 24 V (higher voltages to special order) Current ratings UL: AC 120 V; DC 60 V 0.01...5 A Current ratings 0.01...5 A (higher current ratings to special order) 808 - H - 5 A ordering example Max. continuous load excitation circuit (2-3) 2.65 x I N Max. continuous load Preferred types switching circuit 6-7 auxiliary circuit 4-5 5 A Preferred types Standard current ratings (A) Typical life 6,000 operations 0.02 0.05 0.1 0.3 0.4 0.5 0.6 1 2 3 5 at 5 A for switching circuit x x x x x x x x x x x 808-H- Ambient temperature -30...+70 °C (-22...+158 °F) Insulation co-ordination rated impulse pollution (IEC 60664-1) withstand voltage degree 1.5 kV 2 Standard current ratings and typical internal resistance values Dielectric strength (UL 1077) test voltage Current Internal Current Internal operating area AC 1,240 V rating (A) resistance (Ω) rating (A) resistance (Ω) excitation to switching circuit AC 1,240 V 0.01 625 0.8 0.096 excitation to 0.02 170 0.9 0.085 auxiliary circuit AC 1,240 V Insulation resistance > 100 MΩ (DC 500 V) 0.03 77 1 0.073 Interrupting capacity 0.04 47 1.2 0.050 (o-o-o) 100 A 0.05 29.2 1.5 0.031 Interrupting capacity (UL 1077) 2,000 A AC 120 V 0.08 10.3 2 ≤ 0.02 1,000 A DC 60 V 0.1 5.6 2.5 ≤ 0.02 Degree of protection operating area IP30 (IEC 60529/DIN 40050) terminal area IP00 0.2 1.65 3 ≤ 0.02 Vibration 3 g (57-500 Hz), ± 0.23 mm (10-57 Hz), 0.3 0.89 3.25 ≤ 0.02 to IEC 60068-2-6, test Fc 10 frequency cycles/axis 0.4 0.39 4 ≤ 0.02 Shock 25 g (11 ms) 0.5 0.28 4.5 ≤ 0.02 to IEC 60068-2-27, test Ea Corrosion 48 hours at 5 % salt mist, 0.6 0.198 5 ≤ 0.02 to IEC 60068-2-11, test Ka 0.7 0.143 Humidity 240 hours at 95 % RH to IEC 60068-2-78, test Cab Mass approx. 10 g Approvals Authority Standard Rated voltage Current ratings UL UL 1077 AC 120 V 0.006 A…8 A DC 60 V 0.006 A…8 A AC 120 V 0.006 A…5 A C22.2 No 235 DC 60 V 0.006 A…8 A CSA C22.2 No 235 AC 120 V 0.01...5 A DC 60 V 0.01...8 A 1646 www.e-t-a.de 1 Magnetic Overcurrent Circuit Breaker 808-...
