Mempower Low Power Range Trunking

Low Power Range

The Mempower LP range is available in 40A, 63A, 80A, 100A & 125A ratings.

The attractively styled housing is manufactured from extruded aluminium giving a degree of protection to IP4X (IP54 on request).

The moulded interlocking covers, provide support and insulation for the five copper conductors - 3 phase with separate full size neutral and integral earth conductors. The fifth bar can be specified as a clean earth where required, for example in computer applications.

In these circumstances, the aluminium housing provides a separate protective earth.

Supplied in 3 metre lengths (other lengths available on request) the trunking can be end or centre fed (switched on 40A, 63A and 80A) and is supplied complete with connection blocks for jointing to adjacent lengths or fittings. Three positions for tapping are provided in every metre allowing easy access to tap-off locations via a range of switches and overcurrent protective devices which include MCBs, HRC fuses and RCDs. Tap-off units can be provided with BS 4343 or BS 1363 sockets.
