IDEAL Industries 83-9401 Non-Insulated Female Flag Disconnect, 16-14 AWG, .250", Box of 100

The 83-9401 is sized for 16-14 AWG stranded wire. Its barrel has an expanded insulation entry so it takes a range of insulation diameters on that wire range, and a shouldered insulation barrel that seats the terminal in the crimp tool at the right depth. Going outside 16-14 AWG means a different terminal, not a different crimp setting.

It is a non-insulated terminal, bare tin-plated brass. In a panel or junction box where leads sit close together or near a metal enclosure wall, you will need heat shrink, a nylon or vinyl insulator sleeve, or enough physical separation to keep the crimp from contacting anything. If you want the insulation built in, order an insulated female flag disconnect instead.

No. The 83-9401 is a crimp-on wire terminal that slides onto a .250" tab, not a switching device. If you need a device that opens a circuit, look at a manual or fused disconnect such as the Bryant 30103D 103D Series 600V 3-pole manual disconnect switch, the Square D TeSys GS fused disconnect switch (3-pole, 30A, 600V), or the Square D TeSys VLS rotary handle disconnect. Those break power; the 83-9401 just terminates a wire.

No - despite the shared word "disconnect," these are different classes of product. The IDEAL 83-9401 is a non-insulated female flag disconnect terminal, a crimp-on wire terminal for 16-14 AWG conductors with a .250 inch tab receptacle, supplied in a box. The Bryant 30103D is a 103D Series 600V 3-pole manual disconnect switch - a panel or enclosure mounted switching device that opens a circuit. If you need a crimp terminal to land a wire on a .250 inch male tab, the 83-9401 is the part; a manual switch will not serve that purpose.

The Square D GS1DU3 is a TeSys GS fused disconnect switch rated 3-pole, 30A, 600V - a load-break device that disconnects and fuses a circuit feeding a motor or panel. The IDEAL 83-9401 is a crimp-on female flag terminal for 16-14 AWG wire with a .250 inch tab opening, built from tin-plated brass with internal barrel serrations and a butted seam barrel. One is circuit protection and switching gear; the other is a wire termination consumed by the box on an assembly or control wiring job.

The barrel is built two ways against that. Internal serrations bite into the strands to resist pull-out and cut electrical resistance at the joint, and the barrel uses a butted seam so it will not split open under full crimp pressure. Use the correct 16-14 AWG nest in a ratcheting crimper to get that performance.

Most control panel builds use both, for different jobs. The Square D VLSH2S5B is a TeSys VLS protruding rotary handle disconnect switch with a 65x65 mm handle - the door-mounted operator that isolates the panel. The IDEAL 83-9401 is the crimp terminal used inside the panel to land 16-14 AWG control wiring on .250 inch quick-connect tabs, and ships in a box quantity for repeat use across the build.

The body is brass with tin plating for corrosion resistance, which is the standard material pairing for condenser units, rooftop equipment and other damp-location control wiring. Because the barrel is bare, protect the crimp itself with adhesive-lined heat shrink if it will see direct moisture.

IDEAL Industries part number 83-9401. It is supplied as a boxed quantity for shops doing repeat control and appliance wiring rather than as a single piece.
