| Magnetic Overcurrent Circuit Breaker 808-... Description Single pole miniaturised magnetic circuit breakers with unique highspeed 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. NEW Typical applications Printed circuit boards and components, safety and control systems. 808 Ordering information Type No. 808 fast-acting Manual release (optional) H manual release facility Current ratings 0.01 ...8 A 808 H - 1A ordering example Technical data Voltage rating Current ratings Max. continuous load excitation circuit (2-3) Max. continuous load switching circuit 6-7 auxiliary circuit 4-5 Typical life Ambient temperature Insulation co-ordination (IEC 60664 and 60664A) DC 24 V UL, CSA: AC 120 V, DC 60 V 0.01...8 A 2.65 x IN 3 Packaging quantity: 250 pcs 5A 6,000 operations at 5 A for switching circuit -30...+70 C (-22...+158 F) Rated impulse withstand voltage 1.5 kV Test voltage AC 840 V Pollution degree 2 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 () 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 8 Internal resistance () 0.096 0.085 0.073 0.050 0.031 0.02 0.02 0.02 0.02 0.02 0.02 0.02 0.02 Dielectric strength (IEC 60664 and 60664A) 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 AC 1,680 V > 100 M (DC 500 V) 100 A 1,000 A AC 120 V 200 A DC 60 V operating area IP 30 terminal area IP 00 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 96 hours at 5 % salt mist, to IEC 60068-2-11, test Ka 240 hours at 95 % RH to IEC 60068-2-3, test Ca approx. 10 g Shock Corrosion Humidity Mass Approvals Authority CSA UL Voltage ratings AC 120 V, DC 60 V DC 60 V AC 120 V Current ratings 0.01 ...5 A 0.01 ...8 A 0.01 ...5 A Issue C USA (847) 827-7600 - CANADA (905) 764-9510 171 Magnetic Overcurrent Circuit Breaker 808-...
