Eaton Multiwire Connector Kit for EG-Frame Series G Circuit Breakers, 125A Three-Wire, #14-2 AWG

The Eaton Multiwire Connector is a molded case circuit breaker accessory designed for line and load terminal connections on Eaton EG-Frame, Series G circuit breakers. Rated for 125A applications, this three-wire multiwire connector accepts conductors in the #14-2 AWG range, allowing multiple wires to terminate securely at a single breaker lug. Each kit is UL Listed, giving electrical contractors and panel builders a code-compliant option for multiwire branch circuit terminations.

Key Features

  • Amperage Rating: 125A rating matches EG-Frame Series G breaker terminal capacity for reliable current-carrying performance.
  • Wire Range: Accepts conductors sized #14-2 AWG, giving installers flexibility when terminating multiple circuit conductors.
  • Three-Wire Configuration: Multiwire connector design supports three-wire terminations at a single breaker terminal, reducing the number of breaker poles needed for branch circuits.

Eaton 3TA125E3K – Frequently Asked Questions

1) Will the Eaton 3TA multiwire connector kit fit my EG-Frame Series G breaker?
The Eaton multiwire connector is built for the terminals on Eaton EG-Frame, Series G molded case circuit breakers, and it works on both the line side and the load side of the breaker. If your breaker is a different Eaton frame, this is not the connector for it. Note that the ordering options run by amperage and frame: Frame G at 100 amperes (3TA100G6K) and Frame J-K at 125 and 150 amperes (3TA125E3K, 3TA150F6K), so pick the code that matches the frame you actually have in the panel.
2) What wire sizes can I land in the Eaton 125A three-wire multiwire connector?
It takes conductors from #14 through #2 AWG, and it lands three of them at a single breaker terminal. That range covers typical branch circuit wiring up through larger feeders on a 125A breaker terminal, so an electrician doing multiwire branch circuits does not need a separate connector per conductor size.
3) Which Eaton 3TA part number do I order for a 100A Frame G breaker versus a Frame J-K?
Order by amperage and frame together. 3TA100G6K is the 100 ampere Frame G version. For Frame J-K there are two: 3TA125E3K at 125 amperes and 3TA150F6K at 150 amperes. The frame letter on the breaker label is what decides it, not the circuit ampacity you are wiring.
4) Why use a multiwire connector instead of adding more breaker poles?
A multiwire connector lets three conductors terminate at one breaker lug, so a panel builder can feed multiple branch circuit conductors off a single breaker terminal instead of consuming additional poles. That matters in tight commercial and industrial panelboards and switchgear where pole count is the constraint. It is a terminal accessory, not a breaker, so it does not change the breaker's own trip rating.
5) How many connectors come in one Eaton 3TA kit?
Each kit is supplied with 18 connectors. For a facilities or MRO buyer that means one kit covers a run of terminations across a panel rather than a single breaker, so it suits multi-circuit panel work and keeps spares on the shelf for retrofit of EG-Frame breaker terminals.
