Sta-Kon RZP POLYCRBNT INS PIN TRM .25-.75MM2

The RZP pin terminal takes stranded conductors from 0.25 to 0.75 mm2. In AWG terms that range covers roughly 24 through 18 gauge, so it suits control wiring and small-gauge panel conductors rather than power feeders. If your conductor is larger than 0.75 mm2, you need a different size in the pin terminal range.

A pin terminal like the RZP ends in a solid round pin, so it is meant for clamp or cage-style terminal blocks and spring connectors where a round male end is pushed in and screwed down. A ferrule only consolidates the strands flush with the insulation and adds no reach; a fork or ring terminal is for a screw-and-washer stud. If your block accepts a pin, the RZP keeps the strands from splaying and gives you a repeatable contact. If the device has a screw post, use a ring or fork instead.

The conductor barrel is electrolytic copper, which is what gives the crimp its conductivity and its ability to cold-form around the strands without cracking. The sleeve is polycarbonate rather than vinyl, so it runs harder and holds its shape better at elevated panel temperatures than a soft PVC sleeve would.

Pin terminals are crimped, and crimping is a stranded-conductor operation. The RZP is sized 0.25 to 0.75 mm2 for stranded control wire, where the terminal keeps loose strands from escaping the clamp. Solid wire already holds its shape and can be landed directly in the block, so a crimped pin adds nothing and will not form a reliable joint.

Insulated pin terminals are crimped over the sleeve, so they need a tool with a nest matched to the insulated barrel, not an open-barrel or non-insulated die. Using an uninsulated die on the polycarbonate sleeve will split it. The terminal itself ships as the terminal only, so budget for the tool separately if your crew does not already carry one for 0.25 to 0.75 mm2 insulated terminals.

Green is the insulation color on the RZP, and on insulated terminals the color is a wire-range code, not a decoration. It lets an electrician or inspector confirm at a glance that a 0.25 to 0.75 mm2 conductor was terminated with the matching terminal. Keep the color coding consistent across a panel and troubleshooting later is much faster.

Order it as Sta-Kon RZP. That is the manufacturer part number for the green polycarbonate-insulated pin terminal rated 0.25 to 0.75 mm2, and it is manufactured in Sweden.
