16 / 64 page ![]() Description 2/16 Siemens I 2.1 · 2001 General Data Miniature Circuit-Breakers (MCBs) s Selectivity of MCBs/circuit-breakers In distribution networks without any fuses, MCBs provide selec- tivity between themselves within close limits. This depends on the peak current Î of the downstream MCB and on the tripping current of the upstream MCB. The following table specifies the short-circuit currents in kA up to which selectivity is provided between MCBs connected in series at 230 V AC. Limit values of the MCBs/circuit-breakers selectivity in kA Downstream MCBs Upstream circuit-breakers 5SX4 7 Characteristic C 5SP4 7 Characteristic C 5SP4 8 Characteristic D In [A] 20 25 32 40 50 80 100 80 100 I >[A] 200 250 320 400 500 800 1,000 1,200 1,500 Icn [kA] 10 10 10 10 10 10 10 10 10 Selectivity limits [kA] 1) 5SX2/5SX4 Characteristic B 6 30 6/10 0.2 0.2 0.3 0.5 0.5 0.8 1.5 3 5 10 50 6/10 0.2 0.2 0.3 0.5 0.5 0.8 1.2 3 4 13 65 6/10 0.2 0.2 0.3 0.4 0.5 0.8 1.2 2 3 16 80 6/10 0.2 0.2 0.3 0.4 0.5 0.8 1.2 2 3 20 100 6/10 - 0.2 0.3 0.4 0.5 0.8 1.2 2 3 25 125 6/10 - - - 0.4 0.4 0.6 1.2 1.5 3 32 160 6/10 - - - 0.4 0.4 0.6 1.2 1.5 3 40 200 6/10 - - - - 0.4 0.6 1.2 1.5 2.5 50 250 6/10 - - - - - 0.6 1 1.5 2.5 Characteristic C 0.5 5 6/10 0.2 0.3 0.5 0.8 0.8 1.2 4 6/10 6/10 110 6/10 0.2 0.3 0.5 0.8 0.8 1.2 4 6/10 6/10 1.5 15 6/10 0.2 0.3 0.5 0.8 0.8 1.2 4 6/10 6/10 220 6/10 0.2 0.3 0.5 0.8 0.8 1.2 4 6/10 6/10 330 6/10 0.2 0.2 0.3 0.5 0.5 0.8 1.5 3 4 440 6/10 0.2 0.2 0.3 0.5 0.5 0.8 1.5 3 4 660 6/10 0.2 0.2 0.3 0.5 0.5 0.8 1.5 3 4 880 6/10 0.2 0.2 0.3 0.4 0.4 0.6 1.2 2.5 3 10 100 6/10 0.2 0.2 0.3 0.4 0.4 0.6 1.2 2.5 3 13 130 6/10 0.2 0.2 0.3 0.4 0.4 0.6 1.2 2 3 16 160 6/10 0.2 0.2 0.3 0.4 0.4 0.6 1.2 2 3 20 200 6/10 - 0.2 0.3 0.4 0.4 0.6 1.2 2 3 25 250 6/10 - - - 0.3 0.4 0.6 1 1.5 2.5 32 320 6/10 - - - 0.3 0.4 0.6 1 1.5 2.5 40 400 6/10 - - - - - - 0.8 1.5 2 50 500 6/10 - - - - - - 0.8 1.5 2 63 630 6 - - - - - - 0.8 1.2 1.5 Values for 5SY on request. i21_01.fm Seite 16 Mittwoch, 20.
