Circuit breaker terminal kit · 3-pole 600A · Cu/Al line-load lugs · Eaton 3TA603LDK
3-pole line and load terminal kit for Eaton Series C 600A L-frame moulded case circuit breakers. Accepts copper or aluminium conductors in the 400-500 kcmil range, typically with 2 conductors per terminal depending on breaker and lug configuration.
What this product is for
This terminal kit is used to terminate line and load conductors on compatible Eaton Series C 3-pole 600A L-frame moulded case circuit breakers. It is intended for commercial and industrial distribution equipment where large copper or aluminium conductors must land directly on the breaker.
Use for
- Replacing missing or damaged breaker lugs on compatible Eaton 600A 3-pole breakers
- New panel, switchboard, or distribution equipment assemblies using Eaton L-frame breakers
- Copper or aluminium conductors in the 400-500 kcmil range
Avoid for
- Breakers outside the compatible Eaton Series C L-frame 600A family
- Applications requiring a different wire range, conductor count, or terminal style
- Installations where breaker listing, torque values, or conductor compatibility cannot be confirmed
Best for
Electricians and panel builders servicing Eaton 3-pole 600A breaker installations that need listed line/load lugs for large Cu/Al feeders.
Installed in
Typically installed in switchboards, distribution panels, MCCs, and other commercial or industrial power distribution assemblies using Eaton moulded case breakers.
Why this product exists
Large-frame breakers often require application-specific terminals rather than universal lugs. This kit provides the correct breaker-mounted termination method for compatible Eaton 600A frames, helping maintain fit, conductor range, and listing compliance.
Compared with similar products
Compared with smaller breaker lug kits, this 600A kit is sized for larger feeder conductors and a 3-pole breaker format. Source listings indicate a 2-conductor terminal arrangement and 400-500 kcmil wire range, so it is suited to heavier distribution work rather than branch circuit terminations.
Typical guidance only: always confirm the exact breaker type, frame, and approved conductor range before ordering. Actual compatibility depends on the breaker catalogue number, terminal markings, and local code requirements.
