Abb Installation Products 204210-1h Ring Terminal 12-4 Awg

Product Description

The ABB INSTALLATION PRODUCTS 204210-1h is an insulation-piercing magnet wire ring terminal designed for solid electrical connections in demanding trade applications. Built from copper alloy with a tin-plated finish, this ring terminal accepts wire in the 12 AWG to 4 AWG range, covering 20,760 to 104,960 circular mil area. The 1/4 inch stud size and double-splice configuration make it a reliable choice for licensed electricians working on motor winding connections, control panel terminations, and similar magnet wire installations. The insulation-piercing teeth eliminate the need to strip wire insulation before termination, saving time on the job.

This ring terminal is suited for residential and commercial electrical work where magnet wire connections to stud-mounted terminals are required. Typical applications include motor winding terminations, transformer connections, and control panel wiring. The double-splice design provides added mechanical holding strength. The tin-plated copper alloy construction resists corrosion and maintains reliable conductivity over the service life of the connection.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements. De-energize and lock out the circuit before installing or replacing any terminal connector. Use a properly rated crimping tool to seat the terminal fully onto the wire before stud fastening. Do not overtighten the stud fastener, as this may deform the terminal barrel and compromise the connection.
