Overview

The ABB 204210S Insulation Piercing Magnet Wire Splice is a compact, copper alloy splice designed for direct connection of magnet wires without stripping insulation. Rated for wire ranges from #12 AWG to #4 AWG (10,380 to 52,480 circular mil area), this splice eliminates the need for traditional wire stripping or soldering, reducing installation time and labor costs. The tin-plated copper alloy construction ensures reliable electrical conductivity and corrosion resistance in industrial environments. Measuring 0.69 inches in length and 0.53 inches in width/height, the 204210S is optimized for tight spaces and high-density wiring applications. Ideal for motor windings, transformers, and control panels where space and reliability are critical. Compatible with standard magnet wire insulation types, this splice provides a secure, gas-tight connection that maintains integrity under vibration and thermal cycling. No special tools are required for installation, making it a practical choice for field service and maintenance teams.
