Where the CTL25-12 Crimp Lug Is Used

A compression crimp lug terminates a single conductor end to a bolted connection point — the conductor is inserted into the barrel and a compression crimp tool closes the barrel around the conductor, making a permanent, mechanically secure, low-resistance termination. The tongue of the lug is then bolted to the connection point — a terminal block, earth bar, busbar, equipment stud, or similar — using an M12 bolt through the 12mm stud hole.

The CTL25-12 is sized for 25mm² conductor — a large cable size used in Australian commercial and industrial electrical installations for sub-main feeds, main switchboard incoming cables, large three-phase circuit conductors, and high-current single-phase installations. At 25mm², the conductor is firmly in commercial and industrial territory — single-core or multi-core cables used for main distribution, motor circuits, and heavy current sub-mains. The 12mm stud hole suits M12 hardware — the standard bolt size used on heavier busbars, earth bars, and industrial equipment terminals where a high-current, mechanically robust connection is required. The tinned copper construction combines the excellent conductivity of annealed copper with a tin electroplated surface that resists oxidation and maintains a clean, low-resistance contact at the bolted joint over the service life of the installation.

Crimp lugs in this range are available across a wide range of cable sizes and stud hole combinations — covering the full range of conductor sizes and connection hardware used in Australian electrical installations.

Q: What is the difference between CTL25-10 and CTL25-12?
A: Both are 25mm² tinned copper tube crimp lugs with identical barrel and cable specifications. The only difference is the stud hole — CTL25-10 has a 10mm stud hole (suits M10 bolts) and CTL25-12 has a 12mm stud hole (suits M12 bolts). Select the correct size to match the bolt or stud at the connection point.

Q: What stud or bolt size suits the CTL25-12?
A: The CTL25-12 has a 12mm stud hole, suited to M12 bolts and studs — the standard hardware used on heavier busbars, earth bars, and industrial equipment terminals.

Q: Is the CTL25-12 sold individually or in a bag?
A: The CTL25-12 is sold individually.
