Busbar-mounting fuses cut protection costs

16 May, 2012

At the recent Hannover Fair, Rittal announced a range of easy-to-install fuse bases designed to be mounted on 5 and 10mm-thick busbars. The bus-mounting fuses offer a cheaper alternative to motor circuit-breakers in cost-sensitive applications.

The bases, which mount onto Rittal’s 60mm RiLine60 busbar system, are made of a fibreglass-reinforced, thermoplastic polyester material with a high temperature resistance. A spring-mounted baseplate ensures safe contact with the bus, avoiding damage to the busbar caused by incorrectly inserted or bursting fuses. The large amount of heat given off during fusing is dissipated effectively, avoiding hotspots and ensuring reliable, safe operation of the protective devices.

The bus-mounting fuse bases also offer benefits during installation. For example, they are pushed onto the busbars easily using spring-mounted contact plates. A swivelling plug-in foot allows the bases to be fitted on 5 or 10mm busbars.

Connection clamps accept conductors with cross-sections up to 25mm2. They meet the requirements of the new VDE 0636-3 standard and can carry currents up to 63A.

Assembly can be simplified further using Easy Connect bus-mounting fuse bases with built-in connections. These are simply snapped onto the busbar system and connected directly. No tools are needed, other than a screwdriver. Voltages can be measured via easy-to-reach test points.
