 ATPV32L/ATPV63LD（1#）  ATPV32/ATPV32D（2#）  Comparison Notes

1  Base length
  The length of the ATPV63LD base is 121mm.
 The length of the ATPV32D base is 101mm.
 The two bases differ by 20mm in length and 10mm on each side.

2  Base width

 The width of the ATPV63LD base is 22mm.
 The width of the ATPV32D base is 18mm.
 The difference in width between the two bases is 4mm.

3  Base height

 The height of the base of the ATPV63LD is 67mm.
 The height of the ATPV32D base is 67mm.
 The height of the two bases is the same, and the installation is the same.

4  Core length

 The length of the ATPV32L melt core is 85mm.
 The length of the ATPV32 melt core is 65mm.
 The length of the two cores differs by 20mm.

5  How the core is installed

 Plugin type, 10*85 and 14*85 cores can be installed.
 Plugin type, only 10*65 melt cores can be installed.
 The core installation is the same for both bases.

6  Comparison of base performance

 ATPV63LD has UL, TUV, CE certificates, the maximum current can reach 63A, and the breaking capacity can reach 50kA.
 The ATPV32D has a TUV certificate, and the maximum current can reach 35A breaking capacity to 40kA.
 The maximum carrying current of the two bases is not the same.

7  Comparison of melt core performance

 ATPV32L has UL, TUV, CE certificates, the maximum current can reach 35A, and the breaking capacity can reach 50kA.
 The ATPV32 has a TUV certificate, the maximum current can reach 35A, and the breaking capacity is up to 40kA.
 The longer the melt core, the higher the voltage bearing capacity, the higher the breaking capacity, the better the arc extinguishing, and the faster the fusing speed.
