1 description typical applications current ratings, typical voltage drop values and colour coding technical data single pole, thermal miniaturised circuit breaker designed for automotive applications. fits into fuse blocks designed to iso 8820-3, type f. automatic reset (for dc 12 v only) and open circuit (modified reset to sae) version optional. open circuit version ensures contacts staying open as long as power is on. the circuit breaker will reset after the load is removed. particularly suitable for installation in inaccessible locations. current ratings correspond to those of blade fuses. clear colour coding of the ratings: blade fuse and circuit breaker of the same colour have the same rating. breakers rated 7.5 a through 30 a have a fast characteristic curve and only hold 70 % of their rated current continuously. us patent number: us 8,576,042,b2 protection of electrical systems of passenger cars, trucks, buses, watercraft, extra low voltage wiring systems. 1626-1/-2 1626-3 1626-3h voltage rating 1626-1/-2: dc 12 v 1626-3/-3h: dc 12 v, dc 24 v max. voltage rating 1626-1/-2: dc 14.5 v 1626-3/-3h: dc 29.0 v current ratings 5...30 a 5 a: medium characteristic curve 7.5...30 a: fast characteristic curve service short-circuit breaking capacity 300 operations at 2 x i n ambient temperature -40...+85 c (-40+185 f) (for higher temperatures please enquire) reset period for 1626-1 (at 23 c) 15 s reset period for 1626-2 (at 23 c) after 5 sec at rated voltage < 35 s degree of protection (iec 60529) operating area ip40 (-3) operating area ip50 (-1, -2) terminal area ip00 ultimate short-circuit breaking capacity 3 break operations at 150 a, or 1 break operation at 2,000 a vibration 10 g (57-500 hz), 0.38 mm (10-57 hz) to iec 60068-2-6, test fc 10 frequency cycles/axis sae-j553, step no. 14, 4.2.7.1.5 shock 50 g (11 ms) to iec 60068-2-27, test ea sae-j553, step no. 14, 4.2.7.1.6 corrosion 96 hrs in 5 % salt mist, to iec 60068-2-11, test ka sae-j553, step no. 14, 4.2.7.1.3 humidity 240 hrs in 95 % rh, to iec 60068-2-78, test cab sae-j553, step no. 14, 4.2.7.1.2 mass approx. 3 g caution: it is good practice to switch off the vehicles ignition system before manually releasing or re-setting the circuit breaker. free travel of the reset button must be ensured! please ensure to push in the actuator smoothly and completely. all dimensions without tolerances are for reference only. in the interest of improved design, performance and cost effectiveness the right to make changes in these specifications without notice is reserved. product markings may not be exactly as the ordering codes. errors and omissions excepted. ordering information type no. 1626 single pole thermal mini-cbe with standard characteristic curve version, according to sae j553 1 type 1, dc 12 v automatic reset 2 type 2, dc 12 v modified reset 3 type 3, dc 24 v with reset button 3h type 3*, dc 24 v with reset button and manual release facility current ratings 5 7.5 10 15 20 25 30 a 1626 - 1 - 10 a ordering example current rating (a) voltage drop (mv) housing cap colour 5 < 150 light brown 7.5 < 150 brown 10 < 150 red 15 < 150 blue 20 < 150 yellow 25 < 150 white 30 < 150 light green thermal automotive mini-cbe 1626-... www.e-t-a.de 1646 1
