Rittal's carefully designed air circuit-breaker supporting system

05 September 2017

Rittal has developed a new busbar supporting system for air circuit-breakers, carefully designed to ensure ease of use and faster fitting for system integrators.

The system has been developed to enable 4 x 120 x 10mm coppers to be secured safely to the top and bottom of the air circuit-breaker.

It has been carefully designed to ensure ease of use, maximum convenience and faster fitting for system integrators.

The support, which is suitable for 600 and 800mm wide enclosures, is quick to install within Rittal’s Ri4Power modular switchgear systems, speeding up the time needed for installing air circuit-breakers in Ri4Power. Only part number to order it simplifies the ordering process and reduces stocking levels for the panel builder.  

Installation instructions are straightforward and there is clear guidance on the spacing of the support enabling verification up to 100 kA Icw for one second. 

The new system has been tested in line with IEC 61439 and can be used with all leading circuit-breaker manufacturers’ products up to 4000 amps.
