Sta-Kon C55PT NON-INS PIN TERMINALS 12-10 LG .76

The C55PT accepts 12 to 10 AWG stranded or solid copper wire. One barrel size covers both gauges, so a panel built with mixed 12 and 10 AWG branch conductors can be terminated with the same part and the same crimp die.

It is a non-insulated pin terminal, bare copper with no nylon or vinyl sleeve. If the termination point needs strain relief or a dielectric barrier, you add heat shrink or a separate insulating cap yourself. Bare barrels are what you want where the terminal seats inside an enclosed terminal block or clamp that already provides the insulation.

No. The C55PT carries a 300 V rating, so it is limited to 300 V circuits. For 480 V feeders or motor terminations you need a lug or terminal rated 600 V or higher. The 300 V rating covers most control wiring, lighting circuits, and 120/208 V branch work.

A pin terminal turns stranded wire into a solid pin so it can be clamped in a screw-type terminal block, breaker lug, or contactor pressure plate without strands splaying or backing out under the screw. Ring and fork terminals go under a stud or screw head instead. A butt splice joins two wires end to end and does not land on a terminal at all. If your wire is going into a clamp or box lug, the C55PT is the right style.

Pin length is .76 inch. That matters when the terminal has to bottom out in a deep clamp or pass through a terminal block throat, so measure the depth of the pocket on your block before committing to this one.

The barrel is copper, so it is for copper conductors only. Crimping copper onto aluminum wire creates a dissimilar metal joint that corrodes and loosens. For aluminum branch wiring you need an AL/CU rated connector instead.

Non-insulated barrels crimp with a bare-terminal die, not the color-coded insulated die set. The 12-10 AWG barrel on the C55PT matches the yellow range position on most ratcheting crimp tools, but on a non-insulated frame you use the uninsulated nest of the same gauge range. An insulated-terminal die will deform a bare barrel instead of forming a proper indent.

Country of origin on the C55PT pin terminal is the United States. That is the documentation point most government and institutional procurement packages want on electrical consumables.

Order Sta-Kon C55PT. That single part number covers the 12-10 AWG non-insulated pin terminal with a .76 inch pin, so if the terminals already in the panel are that configuration, the C55PT matches them.
