Cartronix CTX-3421 Mini Double Fuse Holder – Includes 10A Plug-in Fuse

With the Cartronix CTX-3421 mini double fuse holder, you can effortlessly install an additional, well-protected power circuit. Thanks to its compact blade-fuse design, you can easily place this holder into an existing fuse holder—without any cutting or soldering work on the original wiring harness.

You simply place the original fuse back into the first holder and add a new fuse to the second holder for the extra circuit. This way, both the existing and the new system are protected separately.

Why choose the CTX-3421?

✅ Compact size – Especially for smaller fuse boxes and mini fuses
✅ Plug & Play installation – Easy to install, no cutting or soldering required
✅ Safe and reliable – Both circuits separately shielded with their own fuses
