Adjusted current
44 A
Current after application and spare-margin multipliers.
Calculator preliminar
Fuse selection calculator
Select a preliminary fuse family and rating using load current, application type, continuity assumptions, and spare margin.
Assumptions used by this calculator
- Fuse family is selected from application class: gG for general, aM for motor, and aR for semiconductor-focused protection.
- Continuous-load and application multipliers are used for planning only and do not replace manufacturer coordination curves.
- Fault duty, I2t behavior, and upstream/downstream coordination must still be checked before final issue of materials.
Fuse family
gG
Preliminary fuse family selected from the configured application type.
Recommended fuse
50 A
Rounded preliminary fuse size from the adjusted design current.
Engineering note
Review
Use this as a preliminary fuse selection only. Final coordination and fault-duty checks remain mandatory.
