185mm busbar system withstands 50kA for a second
Rittal has launched the Ri4Power modular busbar system with a 185mm busbar centre distance. Ri4Power is suitable for configuring compact, secure power distribution within Ri4Power switchgear systems or Rittal’s renowned TS 8 enclosure range. Offering current ratings of up to 1600A and a short time withstand rating of 50kA for one second, the Ri4Power system meets the current switchgear standard IEC 61439-1.
It is easy to install with no drilling required and integral contact hazard protection, making the system both safe and secure and a quick fix to a punched rail system. The busbar has adaptors ranging from 800 to 1600A for the safe use of standard compact air circuit-breakers available from leading moulded case circuit breaker manufacturers. The circuit breaker can therefore be fitted directly onto the busbar which in turn reduces the amount of space needed within enclosures to accommodate Ri4Power systems.
NH slimline fuse-switch disconnectors are available in single pole or 3-pole versions enabling a very compact busbar distribution system. The design maximises heat flow for optimum heat dissipation within the enclosure.
