20、I 01-2000 3 1 Scope and field of application This standard specifies the required characteristics for three-pole temperature compensated circuit breakers of current ratings from (0,5 to25)A. These circuit breakers are operated by a single push-pull button with trip-free release, delayed tripping and
21、 are explosion proof. Their operation is ensured up to short circuit current. Their temperature range lies between55 C and125 C for I n u 15A and between55 C and90 C for I n 15A, at an altitudeZ=22000mmax. This standard shall be used in conjunction with EN2350. 2 References EN 2282, Aerospace series
