High Voltage Fuse

Our offered Product range includes House Service Cutout, Under Ground Single Pole Cutouts, SINGLE POLE CUTOUTS, Cast Aluminium Cutouts and DMC Heavy Duty Cutouts.

House Service Cutout

The cutouts are designed for 60/80/100A rating complying with BS 7657:1993 and ESI 12-10.
General Construction
The Cutout Housing is of DMC with a quality finish from modern moulding tools to ensure accuracy in the various
parts for interchangeability. Mechanical and Di-electric strength. Brass inserts are provided wherever required for
fixing one part to another. Terminal Blocks are of Brass duly Tin plated, fitted with two large pinching screws per
conductor. The fuse carriers are designed for standard BS 88 / BS 1361 fuse links and standard copper contacts
having uniform pressure to ensure effective contact with long service life.
Following dimensions are standard:
Upto 60/80A 22.23 mm dia.-57 mm long II a
80/100A 30.16 mm dia.-57 mm long II b
Fuse Carriers: These are of split design, therefore it only necessitates to loosen the fuse clips when replacing a
fuse link. Fuse link can be withdrawn from the open end of the carrier half. Carrier housing is common for both 60A
& 100A fuse links. Upgrading of cutout can be done simply by replacing with larger fuse clips.
Sealing: The fuse carrier and fuse base unit have provision for wire sealing. An additional wire sealing
arrangement is provided for the neutral.
Phase Protection: A hinge type nylon shroud covers the incoming phase terminals thus reducing the possibility of
accidental contact with live parts when wiring the outgoing terminal.
