Siemens 3TW1FG350 3 Piece Wrap Around Terminal Kit

Siemens 3TW1FG350 is a three-piece wrap-around terminal kit for FG-frame VL circuit breakers, delivering a secure control-wire connection across three poles. The kit comprises three wrap-around lugs mounted on a steel body (Cu wire only) and is designed for copper conductors sized #4–350 kcmil, with a single-hole TW1FG350 termination per lug. Rated for FG-frame breakers from 40 to 250 A, it provides a ready-made three-position terminal assembly that simplifies field wiring in distribution panels and switchgear. Each lug is built to the wrap-around style used by Siemens for reliable, tight terminations of control wiring in VL FG-frame devices, and the 3-piece configuration ensures consistent assembly across three poles. This accessory is documented in Siemens literature and widely offered by distributors as 3TW1FG350, reflecting its role as a dedicated kit of three copper-wrap terminals for FG-frame breakers.
