The Exel fuseboard range is available with standard enclosures to IP4X for the complete range of 20A to 100A distribution boards. A variety of extra features have been incorporated in the range including increased cabling space, superior door latches and locking devices (there is a choice of barrel lock or padlocking device), improved lid hinges and a unique safety carrier which effectively blanks off a single fuse-way allowing the circuit to be worked on in safety. Safety carriers have no provision for accepting a fuselink.
The Exel distribution fuse boards are designed to comply with the requirements of BSEN 61439-2. All phase parts are fully shrouded so that additional circuits may be wired and connected in safety whilst the existing circuits remain live and on load. The type of enclosure available gives protection to IP4X and is supplied with removable endplates. The range covers a wide variety of ratings from 20–100A; 20A and 32A with up to 12 ways in SPN and TPN configurations; 63A and 100A up to 8 ways in TPN configurations. All ratings available with moulded HRC carriers to BS88: Part 2. Testing has been carried out using Eaton ‘S’ type HRC fuselinks. Fuse base mouldings are of high quality thermosetting material. The fuse units have skirted fuse carriers to prevent accidental contact with live parts when inserting or withdrawing a carrier. Separate shields are provided for the base contacts to prevent accidental contact when the carrier has been withdrawn.
All fuseboards are suitable for systems with a rated insulation voltage Ue 660V AC, 500V DC.
