MEDIUM VOLTAGE DIN Fuse-Links
36kV, Current Limiting Back-Up Fuse-Links, 3.15 to 63 Amps
MV DIN
Standards/Approvals:
DIN 43625, VDE 0670 part 4, VDE 0670 part
402 and IEC 60282-1 (2005)
Catalogue Symbol:
36TDQSJ(amp)

Back-up as IEC 60282-1 (2005)
Description:
A range of medium voltage DIN Fuses,
complete with sealed striker, suitable for
transformer protection. The fuses can be
used even where there is no secondary LV
protection, provided they are used with fuse
switches fitted with instantaneous striker
tripping.
All fuse-links are individually.

NOTES
1. CURVES SHOW EXTREME MAXIMUM VALUES WHICH WILL NOT BE EXCEEDED UNDER CONDITIONS STATED IN 2 AND 3
BELOW.
2. FOR HIGH VALUES OF PROSPECTIVE CURRENT A SYMMETRICAL FAULT GIVES THE HIGHEST CUT-OFFCURRENT. FOR
LOW VALUES OF PROSPECTIVE CURRENT, WHERE THERE IS LITTLE OR NO CURRENT LIMITATION, AN ASYMMETRICAL
FAULT PASSES THE HIGHEST PEAKCURRENT. THE CURVES ARE THEREFORE BASED ON THE DEGREE OF ASYMMETRY
WHICH GIVES THE MAXIMUM CUT-OFF CURRENT AT ANY PARTICULAR VALUE OF PROSPECTIVE CURRENT.
3. CURVES RELATE TO FREQUENCY OF 50 Hz AND A RECOVERY VOLTAGE EQUAL TO THE FUSE RATED VOLTAGE.
