Systempro M compact ®Technical detailsParticular supply sources and loadsMCBsIn lighting systems protection against overloads is not necessary if the number of light points is clearlydefined (no overloads).Moreover, the Standard in force for these systems recommends the omission of protection againstoverloads in circuits in which unwanted tripping may prove hazardous, e.g.: circuits which supplyfire-fighting equipment.Single-phase transformer (primary voltage 230 V)-1P and 1P+N MCBsPn [kVA] In [A] ucc (%) Circuit-breaker on primary side (1) and (2)0.1 0.4 13 S 2* D1 o K10.16 0.7 10.5 S 2* D2 o K20.25 1.1 9.5 S 2* D3 o K30.4 1.7 7.5 S 2* D4 o K40.63 2.7 7 S 2* D6 o K61 4.2 5.2 S 2* D10 o K101.6 6.8 4 S 2* D16 o K162 8.4 2.9 S 2* D16 o K162.5 10.5 3 S 2* D20 o K204 16.9 2.1 S 2* D40 o K405 21.1 4.5 S 2* D50 o K506.3 27 4.5 S 2* D63 o K638 34 5 S 290 D8010 42 5.5 S 290 D10012.5 53 5.5 S 290 D100Single-phase transformer (primary voltage 400 V)-2P MCBsPn [kVA] In [A] ucc (%) Circuit-breaker on primary side (1) and (2)1 2.44 8 S 2* D6 o K61.6 3.9 8 S 2* D10 o K102.5 6.1 3 S 2* D16 o K164 9.8 2.1 S 2* D20 o K205 12.2 4.5 S 2* D32 o K326.3 15.4 4.5 S 2* D40 o K408 19.5 5 S 2* D50 o K5010 24 5 S 2* D63 o K6312.5 30 5 S 2* D63 o K6316 39 5 S 290 D8020 49 5 S 290 D100Three-phase transformer (primary voltage 400 V)-3P, 3P+N and 4P MCBsPn [kVA] In [A] ucc (%) Circuit-breaker on primary side (1) and (2)5 7 4.5 S 2* D20 o K206.3 8.8 4.5 S 2* D20 o K208 11.6 4.5 S 2* D32 o K3210 14 5.5 S 2* D32 o K3212.5 17.6 5.5 S 2* D40 o K4016 23 5.5 S 2* D63 o K6320 28 5.5 S 2* D63 o K6325 35 5.5 S 290 D8031.5 44 5 S 290 D8040 56 5 S 290 D8050 70 4.5 S 290 D10010S 2*.. = S 200, S 200 M, S 200 P(1) With modular or magnetic only circuit-breakers, without thermal adjustment, thermal protection is required for the transformer’ssecondary winding.(2) Breaking capacity selected according to estimated Icc at the point where the breaker is installed.Selection tables ............................... pag. 2/2ABB10/75
