Rittal has launched a new power modular system designed to improve protection against accidental arcing in electrical switchgear systems. Preventing accidental arcing was the key objective when developing the Ri4Power modular system because it can lead to both production downtime and is a danger to personnel.
Rittal carried out extensive testing to ensure that the Ri4Power complies with the stringent IEC 61641 standard. Segregation and insulation of busbars ensures that screws and tools can no longer become in contact with unprotected busbars, functional units and terminals, thus reducing the risk of internal arcing.
In line with IEC61641 Rittal’s Ri4Power system utilises pressure relief covers. These covers reduce excessive pressure and explosive gasses in the Rittal Ri4Power switchgear within 30ms. During any internal arcing faults the doors and covers must not open causing dangers to personnel.
