The Domus TRAK 3-circuit mini straight live joiner connects two lengths of track end to end,in line, carrying all three circuits through.308040mm, 240V, IP20, inblack or white.

“Mini” means it is a shorter joiner 80mm long against thestandard part. What no source states is what else differs, so the honestanswer is that the length is the difference we can evidence.

Why a shorter joiner is worth having: the joiner interrupts the track, and anywhere itsits is a stretch where no fitting can be clipped in. On a run where a junction falls close to where youwant a light over the end of an island, at a corner of a display a shorter joinergives back usable track.

Tell us the run and where the joins fall and we will say whether the mini or thestandard joiner suits, and confirm the difference with Domus.

It is a LIVE joiner, and the current rating is not recorded

• “Live” means all three circuits pass through it. Everything downstream of this joinerdraws its power through it.
• That makes its ampere rating as consequential as the feed’s a run fedadequately at one end can still be limited by a joiner in the middle.
• No ampere rating appears in any source we hold, for this part or for the other sixTRAK components in this catalogue. Domus’s own prose calls the system capable of high powerloads and gives no figure.
• The datasheet attached is the track’s, and its parts list does not contain thisjoiner.
• Tell us the fittings on each side of the join and we will get the rating from Domusbefore the layout is fixed.

Where a straight joiner is and is not the answer

• Two lengths in line, on the same plane extending a run past the length of asingle piece of track.
• Not for a corner. A 90 turn needs an angled joiner.
• Not for feeding power in. A joiner connects track to track; a live end or a centrefeed brings the supply in. If your join is also where the cable arrives, thecentre feed live joiner does both in one part.
• Plan the join positions with the fitting positions, not separately. That is thewhole reason a mini joiner exists.

Planning the run

• Track lengths 1m surface-mount and other sizes.
• A feed a live end in the correct hand, or a centre feed live joiner.
• Joiners at every junction this mini straight, a standard straight, or anangled one.
• Dead ends at every terminating end.
• Tell us the total length and shape and we will list every piece. A run that is onejoiner short stops on the day.

Three circuits through the join

• All three circuits carry through, so a fitting on the far side of a join can be set toany of the three exactly as one before it can.
• The conductor order has to stay consistent across the join which isautomatic if the track is oriented the same way, and is the same consideration that decides whether afeed is left or right handed.
• Fittings can still be moved freely along the run after installation, on either sideof the join.

Where it works

• Joining two lengths of track in line, carrying all three circuits.
• Where a junction falls close to a wanted fitting position the shorter body gives backusable track.
• Not for a corner use an angled joiner.
• Not for bringing power in use a live end or a centre feed.
• Indoor only IP20.
• Do not plan a load through it until we have the current rating.

Specifying it

3-circuit mini straight live joiner. 308040mm,240V AC, IP20. Black (22162) or white (22163). Connects two lengths of track end to end inline, carrying all three circuits through. Part of the modular TRAK 3-circuit system.

Current rating, maximum load and conductor configuration are not recorded in any source wehold, and the datasheet attached is the track’s, not this joiner’s. What distinguishesthe “mini” from the standard straight joiner beyond its length is not stated in any source.Tell us the run, where the joins fall, and what is hanging on each side, and we will confirm boththe right joiner and the rating with Domus. Warranty 3 years.

Questions

What does “mini” mean here?

That it is a shorter joiner 80mm long and that is the difference we can evidence, because no source states what else differs from the standard straight joiner. The reason a shorter one is worth having is practical: a joiner interrupts the track, and wherever it sits no fitting can be clipped in. Where a junction falls close to a wanted light position, a shorter joiner gives back usable track.

Can I use it to turn a corner?

No this joins two lengths in line, on the same plane. A 90 turn needs an angled joiner. Tell us the shape of the run and we will list the right junction parts rather than have you discover it with the track already up.

Does it bring power into the track?

No. A joiner connects track to track; power comes in through a live end or a centre feed. If your join is also the point where the supply cable arrives, the centre feed live joiner does both jobs in one part which is often the tidier answer when replacing an existing central ceiling point with a track run.

How much load can pass through it?

Not recorded in any source we hold, and it matters here as much as at the feed: “live” means all three circuits pass through, so everything downstream draws its power through this joiner. A run fed adequately at one end can still be limited by a joiner in the middle. Tell us what is hanging on each side and we will get the rating from Domus.

Can fittings still be set to any circuit after the join?

Yes all three circuits carry through, so a fitting on the far side can be set to any of them exactly as one before it can, and fittings can still be moved freely along the run. What has to stay consistent is the conductor order across the join, which is automatic if the track is oriented the same way.

What else does the run need?

Track lengths, a feed in the correct hand, joiners at every junction, and dead ends at every terminating end. A run that is one joiner short stops on the day, so tell us the total length and shape and we will list every piece.

Can it go outdoors?

No. Like the rest of the TRAK system it is IP20, indoor dry areas only track carries exposed conductors by design.
