Frequently Asked Questions
What type of fuse class is the KTK-3?
It is a midget supplemental fuse intended for fast-acting protection in compact electrical assemblies.
Does this fuse include an indicator?
No, it is a non-indicating type, so it does not feature a built-in blown fuse signal.
What holders are compatible with this fuse?
It fits standard midget-style fuse holders sized for 13/32 in by 1-1/2 in fuses.
Where is this fuse typically installed?
It appears in control panels, lighting circuits, transformer primaries, and other compact high-voltage applications.
You can pair its transformer primary protection role with the fast-acting supplemental design when placing it into a midget holder inside your control panel.
