Rittal 9342240 – Frequently Asked Questions
1) Will the Rittal 9342240 adapter fit my busbar system, and what bar spacing does it need?
The 9342240 connection adapter is built for busbar systems on 60 mm center-to-center spacing, and it suits busbars of 5 mm or 10 mm height. If your bars sit on a different pitch or are a different thickness, this adapter will not seat correctly. It mounts in the Rittal busbar supports 9340.050, 9341.050 or 9342.050.
2) What size conductors can I land on a Rittal 9342240 busbar adapter?
Three connection options. Round conductors, fine wire with a wire end ferrule, are accepted from 10 to 25 mm2. Multi-wire round conductors are accepted from 16 to 35 mm2. For laminated copper bars, the clamping area is 10 x 7.8 mm (W x H). The cable outlet is at the bottom of the adapter, so plan your wire routing downward.
3) What short circuit current rating does the Rittal 9342240 carry, and what protection do I need upstream?
The adapter is UL Listed with SCCR ratings that depend on the upstream device: 50 kA at 600 V with a class K5 fuse rated max 125 A (JDDZ/7), 65 kA at 480 V with a circuit breaker max 125 A (DIVQ/7), and 65 kA at 600 V with a class J fuse max 400 A (JDDZ/7). Those UL ratings apply only in AC applications.
4) How much current can one Rittal 9342240 adapter carry on a three phase feed?
Max rated current is 125 A across its three poles at 690 V, 3 phase. For a feeder above 125 A you need a larger adapter, even though the adapter will sit behind a class J fuse rated up to 400 A for short circuit withstand purposes.
5) Does the Rittal 9342240 come as a single adapter or a multi-pack, and what does it weigh?
It ships one piece per packaging unit, at 0.38 kg per unit, with 0.052 kg of copper per piece. Order one per connection point you are feeding off the bars.
6) What is the Rittal part number for this 3-pole 125 A busbar connection adapter?
Rittal 9342240. It is the 3-pole connection adapter for 60 mm center-to-center busbar systems, rated 690 V 3 phase and 125 A max.
7) Will the Rittal 9342240 adapter match the grey of my existing Rittal enclosure components?
The housing is RAL 7035 light grey, the standard color across Rittal panel components, so it blends with existing Rittal busbar supports and enclosure interiors.
