808-B-1A

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. 808 Ordering information Type No. 808 fast-acting Manual release 01 press-to-reset button, blue B manual release facility, blue (Standard) Current ratings 0.01...5 A 808 - B - 5 A Technical data Voltage rating Current ratings ordering example Standard current ratings and typical internal resistance values Current rating (A) 0.01 0.02 0.03 0.04 0.05 0.08 0.1 0.2 0.3 0.4 0.5 0.6 0.7 Internal resistance (Ω) 625 170 77 47 29.2 10.3 5.6 1.65 0.89 0.39 0.28 0.198 0.143 Current rating (A) 0.8 0.9 1 1.2 1.5 2 2.5 3 3.25 4 4.5 5 Internal resistance (Ω) 0.096 0.085 0.073 0.050 0.031 ≤ 0.02 ≤ 0.02 ≤ 0.02 ≤ 0.02 ≤ 0.02 ≤ 0.02 ≤ 0.02 Ambient temperature Insulation co-ordination (IEC 60664-1) Dielectric strength (UL 1077) operating area excitation to switching circuit excitation to auxiliary circuit Insulation resistance Interrupting capacity (o-o-o) Interrupting capacity (UL 1077) Degree of protection (IEC 60529/DIN 40050) Vibration Approvals Authority CSA UL Max. continuous load excitation circuit (2-3) Max. continuous load switching circuit 6-7 auxiliary circuit 4-5 Typical life Voltage ratings AC 120 V; DC 60 V DC 60 V AC 120 V Current ratings 0.01...5 A 0.01...5 A 0.01...5 A Shock Corrosion Humidity Mass Issue C www.e-t-a.com DC 24 V (higher voltages to special order) UL: AC 120 V; DC 60 V 0.01...5 A (higher current ratings to special order) 2.65 x IN 5A 6,000 operations at 5 A for switching circuit -30...+70 °C (-22...+158 °F) rated impulse pollution withstand voltage degree 1.5 kV 2 test voltage AC 1,240 V AC 1,240 V AC 1,240 V > 100 MΩ (DC 500 V) 100 A 2,000 A AC 120 V 1,000 A DC 60 V operating area IP30 terminal area IP00 3 g (57-500 Hz), ± 0.23 mm (10-57 Hz), to IEC 60068-2-6, test Fc 10 frequency cycles/axis 25 g (11 ms) to IEC 60068-2-27, test Ea 48 hours at 5 % salt mist, to IEC 60068-2-11, test Ka 240 hours at 95 % RH to IEC 60068-2-78, test Cab approx. 10 g 3-5 3 Magnetic Overcurrent Circuit Breaker 808-...
