Busbar fuses mount directly or onto enclosure plate

RITTAL Busbar fuse bases range from 100amps to 630amps and can be mounted either directly onto busbar systems or onto enclosure mounting plates. Fuse monitoring enables fast fault diagnostics via a signal, which is sent to advise of a blown fuse. Fuses are quick and easy to install due to a special locking mechanism and a special switching aid pre-stresses the contact when the fuse base lid is closed, enabling the fuse to slide reliably into its final position without any damage to the contact.
