Weidmüller UL 18 mm Insulated Wire Ferrules
Finish stranded copper conductors with genuine Weidmüller insulated wire-end ferrules. Their extended 18 mm tinned copper sleeves suit compatible Victron MultiPlus-II AC wiring terminals that specify an 18 mm ferrule.
Available in 10 AWG (6 mm²), 8 AWG (10 mm²), and 6 AWG (16 mm²), with colour-coded insulating collars. These ferrules are included in Weidmüller's UL 486F certified crimping system (file E499744).

Frequently Asked Questions
Why do some Victron MultiPlus-II models need 18 mm ferrules?
Certain MultiPlus-II AC terminals specify an extended 18 mm sleeve. Ordinary short ferrules may not meet that terminal's installation instructions. Measure the metal sleeve, not the plastic collar, and follow the manual for your exact unit.
Are these ferrules UL certified?
These Weidmüller ferrules are included in a UL 486F certified crimping system under file E499744. Certification depends on using an approved ferrule-and-crimping-tool combination; it does not apply automatically to every tool or crimp.
Can I use these ferrules outside of Victron installations?
Yes, where the equipment accepts the chosen conductor size and an insulated ferrule with an 18 mm metal sleeve. Use a suitable ferrule crimping tool and follow the terminal manufacturer's instructions.
