Rittal’s busbar system for ac and dc applications

Efficient drive systems, idle power loss reductions and the renewable energy sector all require safe, reliable dc systems and while they cannot replace ac applications across the board, they are definitely growing in importance.

Rittal is the world’s first manufacturer to offer an approved busbar system with standard components, optimised for both ac and dc applications. No other products are required.

DC busbar systems are increasingly deployed in converter buses, dc power back-up systems, photovoltaics, galvanics, energy storage systems and in shipbuilding. Rittal’s RiLine has a current carrying capacity of up to 1,600A, a nominal voltage of up to 1,500Vdc and a short-circuit rating of up to 40kA. It is approved to IEC 61439 and UL 845 in conjunction with UL 508, making it suitable for a wide range of industries.

Depending on requirements, busbar systems can be made of copper, aluminium or cuponal, a copper-clad aluminium busbar from Rittal. RiLine’s assembly parts, such as connection adapters up to 800A, OM component adaptors with tension spring clamps and CB Series compact circuit breaker adaptors up to 250A, are suitable for dc applications.

The following fuse components can be deployed: size 00-3 NH bus-mounting fuse bases up to 630A and size 00 NH slimline fuse-switch disconnectors up to 160A, with corresponding dc fuses.
