Following comprehensive testing Rittal are pleased to announce that their modular Ri4Power system now complies with the latest IEC 61439-2 standards. The termination of cables to switchgear and meeting the form 4b requirement of IEC 61439-2 now enables installation engineers to reduce time and costs on site. Rittal’s RPE software is available for customers to build Ri4Power to the IEC 61439-2 standard.

Motor control centres and electrical distribution switchboards conforming to Form 4b require that cables should be terminated to outgoing devices in their own individual enclosures and should be segregated from the functional unit. In Ri4Power outgoing cables are terminated in a form 4b terminal box which can be easily fitted allowing easy access for the installation engineer.

Designed for both the electrical distribution and motor centre market Ri4Power incorporates Rittal’s leading TS 8 enclosure technology which enables the utilization of standard components. Using the Maxi PLS busbar arrangement the connection to air circuit breakers of multiple cables per phase can be easily achieved. (The Maxi PLS is available in ratings up to 4000A). Sliding fixing nuts located in the Maxi PLS allows the installation engineer full flexibility when terminating incoming cables. Connection from the Maxi PLS to the air circuit breaker is achieved by fully tested copper bar connections.
