Rittal 9340050 – Frequently Asked Questions
1) What size flat copper busbar does the Rittal 9340050 busbar support accept?
The Rittal 9340050 takes flat copper bars from 15 x 5 mm up to 30 x 10 mm. Anything outside that cross-section range will not seat correctly, so measure the bar stock before ordering. Pole spacing is fixed at 60 mm center-to-center, which also has to match your existing panel layout.
2) What SCCR can I claim on a control panel using Rittal 9340050 busbar supports?
UL short-circuit current ratings for the 9340050 run from 14 kA to 73 kA at 480-600 V, and the number you can use depends on the spacing between supports and the busbar dimensions you install. The tested combinations include Class L fuses up to 800 A (JDDZ/7) and circuit breakers up to 600 A (DIVQ/7), so the upstream protective device is part of the rating too.
3) I need a 4-pole busbar arrangement with a neutral bar. Is the 9340050 the right part?
No. The 9340050 is a 3-pole support only, fixed at 60 mm pole spacing. For a four-bar arrangement with a neutral you need a 4-pole support from the same Rittal busbar support range rather than doubling up on this one.
4) Is the Rittal 9340050 busbar support flame retardant for use inside an enclosure?
The support is molded polyamide with fire protection corresponding to UL94-V0, which is why it is used inside switchgear and industrial control enclosures where the insulating parts have to be flame rated.
5) How many Rittal 9340050 busbar supports come in a package?
The 9340050 ships 4 pieces per packaging unit, at 0.696 kg per unit. Plan quantity around your support spacing, since the SCCR you achieve depends on how close together the supports are set along the bar run.
6) Does the Rittal 9340050 come with mounting hardware or do I need a separate bracket?
It is supplied with internal attachment, so the support itself provides the fixing point for securing it in the panel. The bars are clamped by the support; you still supply the copper bar stock and any end-connection hardware.
7) Will the Rittal 9340050 match the gray finish of my existing panel components?
The support is RAL 7035 light gray, the standard enclosure gray Rittal uses across its panel line, so it blends with existing Rittal interior components.
