Fuse protected selection type 2, lq = 50kA, IS/IEC: 60947-4-1
• The selection is valid only for complete Siemens combinations i.e. SDF + DIN Fuse + Contactor + Birelay (+ timer).
• In case this combination is changed to accommodate another brand/rating of SDF/DIN Fuse/Contactor/BMR, it shall be the responsibility of
the person making such a change to assure type 2 performance.
• Selection is for normal starting conditions with starting time ≤ 6 seconds. For heavy starting applications (e.g. ID/FD fans, reciprocating
compressors, ball mills etc.), please consult Siemens.
• At 60°C service temperature the bi-relay has to be derated. The bi-relay can be used upto the maximum current setting indicated. For example - A
bi-relay with setting 32-50A, at 60°C can be used only upto 47A. This however does not mean that at 60°C, the 50A setting corresponds to 47A. It
means that, the bi-relay should not be set beyond 47A.
• The electronic star-delta timer type 3RP should be used in star-delta feeders.
• SDF: Switch Disconnector Fuse. All fuses are DIN HRC type.
• Tested Type 2 combinations
• Low LCC = Low Life Cycle Cost
