3M MVU18-250DFX – Frequently Asked Questions

1) What wire sizes does the 3M Scotchlok MVU18-250DFX female disconnect crimp onto?
The MVU18-250DFX takes 22 through 18 AWG stranded or solid conductor. Red insulation is the standard color code for that range, so if you are pulling terminals out of a mixed bin the red barrel is your 22-18. For 16-14 AWG you need a blue terminal instead, and for 12-10 AWG a yellow one; forcing a heavier conductor into this barrel will not crimp properly.
2) Can I use this disconnect on 24 volt HVAC control wiring and line voltage too?
Both. The terminal carries a 600 V maximum recommended voltage rating, which covers 24 V thermostat and control circuits as well as 120/277 V line voltage work inside panels and equipment. Temperature ceiling is 105 C (221 F), enough for typical furnace and air handler cabinet wiring.
3) Will the insulation on my wire fit inside the terminal sleeve?
The red vinyl sleeve on this Scotchlok disconnect accepts wire insulation up to 0.145 inch (3.7 mm) outside diameter, with the barrel bore itself at 0.080 inch for the bare conductor. Most 22-18 AWG THHN, appliance wire and thermostat cable falls under that. Heavily jacketed or double-insulated 18 AWG can exceed 0.145 inch, in which case the sleeve will not seat over the insulation.
4) Is this 3M Scotchlok terminal flame retardant or filled with anti-corrosion grease?
Neither. The MVU18-250DFX is a plain vinyl insulated disconnect, not flame retardant rated, and the barrel is not grease filled. For wet, buried or corrosive locations you want a gel-filled or heat shrink sealed disconnect rather than this one. Indoors, in panels, equipment cabinets and control circuits, the standard vinyl body is what most jobs use.
5) Should I use a female disconnect or a ring terminal on control equipment?
Use the female disconnect where the device has a male spade tab and you want to pull the wire off without tools, which is most of the time on contactors, limit switches, fan motors and thermostats. Use a ring terminal where the connection is a screw stud and vibration or a code requirement means the wire must not be able to slip off. The MVU18-250DFX is the quick-disconnect half, sized for a 0.25 inch tab.
6) How much room do I need behind the terminal in a tight junction box?
Overall length of the crimped terminal is 0.87 inch (22.09 mm), with a 0.37 inch overall width and 0.23 inch body diameter. Add wire bend radius on top of that when you are stacking several onto a relay or into a crowded control box.
7) What is the barrel construction on this Scotchlok disconnect, and does it matter for crimping?
It is a butted seam barrel in ETP copper, 0.25 inch long. Butted seam means the metal is rolled closed rather than brazed, so crimp it with the die seam facing up in the tool, the way you would any insulated barrel terminal. ETP copper is the standard high conductivity grade, and the terminal is made in the USA.
8) How many 3M MVU18-250DFX disconnects come in a pack?
They ship 100 to a bottle, 3M part number MVU18-250DFX, manufacturer catalog number 7000133356. That quantity suits an MRO crib or a service van restock rather than a single repair.
How fast can I get the 3M MVU18-250DFX delivered?
