Lawson Type “J” fuse-links are for use in a.c. electricity supply networks. They are installed in distribution boards, feeder pillars, link boxes, pole mounted cut-outs and heavy duty service intakes. The range includes all the current ratings specified in BS88-2 and BS 7656 for fuse-links with the standard 82mm and 92mm fixing centres, together with additional non-standardised fuse-links with 76mm fixing centres and female contact fuse-links.
Notes:
- JPU450, 500, 560, 630A are restricted to intermittent loading when installed in 400A fixed contacts
- JSU800A is restricted to intermittent loading when installed in 630A fixed contacts
- IEC60269 and BS88-2 specify performance requirements up to 630A fixed contacts, therefore the performance of JSU800A fuse-links complies with the Breaking Range and Utilisation Category “gG”
