3M 7000133400 – Frequently Asked Questions
1) Will the 3M Scotchlok female disconnect fit a 1/4 inch male tab?
Yes. The Scotchlok nylon insulated female disconnect mates with a 0.25 inch (6.35 mm) male tab, which is the standard quarter-inch blade used on most appliance, motor and HVAC terminals. Connection width is the same 0.25 inch, so it slides straight onto a standard 1/4 in tab spade.
2) What wire size and insulation diameter will this Scotchlok disconnect accept?
The barrel takes conductor insulation up to 0.145 in (3.7 mm) outside diameter, and the barrel itself is 0.25 inch long with a 0.23 inch overall diameter. If the jacket on your wire is fatter than 0.145 in, it won't seat in the barrel and you need a larger terminal.
3) Can I use these disconnects in a 600V lighting or building wire circuit?
Yes. The Scotchlok female disconnect is rated 600V for building wire and 1000V for signs, fixtures and luminaires, with a maximum recommended voltage rating of 600V. It carries UL file number E70512.
4) Will these hold up inside a hot equipment enclosure or rooftop unit?
Temperature range runs -40 to 221 degrees F (-40 to 105 degrees C), which covers rooftop HVAC cabinets and most motor and ballast compartments. The nylon insulation is not flame retardant, so where a flame-retardant terminal is specified, choose a different part.
5) What metal are these terminals made from, and will they corrode in a damp panel?
The terminal body is brass/ETP copper with corrosion-resistant tin plating, which is what gives it conductivity and keeps surface corrosion down in humid locations. There is no grease fill for corrosion protection, so for direct-burial or standing-water conditions you want a sealed or grease-filled connector instead.
6) How many 3M Scotchlok female disconnects come in a bottle or a case?
Two bottle counts are sold, 100 per bottle (MPN 7000133350) and 50 per bottle (MPN 7000133400), and a full case is 500 pieces. For fleet or MRO stocking, the 100-count bottle is the usual shelf unit.
7) Are these 3M disconnects RoHS compliant and made in the USA?
Both. The Scotchlok female disconnect is RoHS 2011/65/EU compliant without exemption and is manufactured in the United States, which covers most government and institutional procurement requirements on origin and substance restriction.
8) Should I use a female disconnect or a ring terminal for this connection?
Use the female disconnect where the wire has to come apart for service without tools, for example a motor, a ballast, or a fixture that gets swapped. It pushes onto a 0.25 inch male tab and pulls off. Use a ring or fork terminal instead where the conductor lands under a screw or stud and is meant to stay put. The dents and rolled edges in this terminal are what give it holding force on the tab.
9) Is the insulation on these disconnects nylon or vinyl, and does it matter?
Nylon, and it matters. The Scotchlok disconnect is a fully insulated nylon terminal, which is tougher and handles higher temperature than vinyl, and the butted-seam barrel makes wire insertion easier. Nylon is the usual choice on commercial and industrial work where the terminal gets pulled on and off during service.
