Exel Distribution Fuseboards

The Exel fuseboard range is available with enclosures giving protection to IP4X.

A variety of extra features have been incorporated into 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.

Exel distribution fuseboards are designed to comply with the requirements of BS 5486: Part 11. All live parts are fully shrouded so that additional circuits may be wired and connected in safety whilst the existing circuits remain live and on load. IP4X enclosures are supplied with removable endplates.

The range covers a wide variety of ratings from 20-200A; 20A and 32A with up to 12 ways in SPN and TPN configurations; 63A up to 10 ways, 100A up to 8 ways and 200A up to 6 ways in TPN configurations.

All ratings are available with moulded HRC carriers to BS 88: Part 2. Testing has been carried out using Eaton MEM 'S' type HRC fuselinks. Fuselinks are not fitted and should be ordered separately.

The exclusive use of Eaton MEM fuselinks will extend the warranty period to 3 years.

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 Separate shields are provided for the base contacts to prevent accidental contact when the carrier has been withdrawn.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.

Enclosures
Rust protected sheet steel enclosures have a light grey paint finish and are fitted with integral fixing holes. Enclosures have a robust, reliable construction.

Enclosures for units from 20A to 100A are also of all welded construction, 200A IP4X units have cast corner pieces. Removable top and bottom endplates incorporate knockouts on 20A and 32A units while 63-200A boards have blank endplates. Blank endplates are available on request for 20A and 32A boards.

Gasketed access doors can be reversed for left hand or right hand opening.

All sides are free from external projections and fuseboards can be mounted in inverted form if required.

Main Terminations
32A, 2 way fuseboards have the main phase termination (tunnel type) attached to the fusebanks. All other fuseboards have the main terminations mounted on the back of the enclosure and are intended for use with cable sockets (sweating or crimp type) which are not provided. Busbar and main terminals are fully shrouded. A cable shroud to cover the cable socket is provided.

Earthing and Neutral Bars
Multi-way earthing bars are fitted with an integral earth bolt and have an outgoing terminal per fuse. They are rail mounted adjacent to the fully rated neutral bars. Neutral bars have main terminals of the same capacity as the phase terminals and have one outgoing terminal per fuse. Earth/neutral bar rails are fitted at the bottom of enclosures on 20A and 32A fuseboards and at the top on all others.
