Improved Arcing Protection
02 November 2012
As well as leading to production downtime, arcing is a danger to personnel.
With this in mind, when developing its Ri4Power modular system a key objective for Rittal was protection against accidental arcing.
Rittal carried out extensive testing to ensure that the Ri4Power complied with the stringent IEC 61641 standard. Segregation and insulation of busbars ensures that screws and tools can no longer come in to contact with unprotected busbars, functional units and terminals, thus reducing the risk of internal arcing.
In line with IEC61641 the Ri4Power system utilises pressure relief covers. These covers reduce excessive pressure and explosive gasses in the Rittal Ri4Power switchgear within 30ms.
