Rittal is launching a new modular Ri4Power busbar system with a 185mm busbar centre distance. The Ri4Power 185mm busbar system is suitable for configuring compact, secure power distribution within Ri4Power switchgear systems or Rittal's TS 8 enclosure range. Offering current ratings of up to 1600A and a short time withstand rating of 50kA for 1s, 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 800A to 1600A for the safe use of standard compact air circuit-breakers available from 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 new design maximises heat flow for optimum heat dissipation within the enclosure.
