المميزات والفوائد
- Combined NH fuse holder and isolating switch in a single type-tested device reduces panel footprint compared to separate fuse holders plus a disconnecting switch in industrial distribution boards.
- Vertical NH fuse extraction under live conditions using a certified insulated fuse puller eliminates the need to de-energise the distribution board for routine fuse replacement at continuously operating process plants.
- NH fuse link independence from switch body allows protection characteristics (gG, gM, aM) and current rating to be changed by replacing only the fuse link, optimising coordination without replacing switch hardware.
- Breaking capacity up to 120 kA with NH gG fuses provides the highest LV fault current interruption capability, meeting prospective fault levels at large transformer LV terminals and generator-backed substations.
- Padlockable rotary handle in OFF satisfies LOTO isolation requirements for individual feeder circuits at Saudi industrial distribution boards.
- NH size range 00–3 in a common product family covers all industrial feeder current ratings from 100 A motor feeders to 1250 A main distribution incomers from a single procurement source.
- Optional auxiliary contact provides remote confirmation of isolation status for unmanned distribution boards at remote Saudi pumping and utility facilities.
التطبيقات الصناعية
- Industrial feeder protection in main distribution boards at SABIC petrochemical sub-distribution panels, where 3NX8 high breaking capacity protects circuits from transformer-backed fault currents exceeding 50 kA.
- Transformer LV terminal protection at industrial substations serving MARAFIQ utility customers, where NH aM motor fuse links provide back-up protection for the LV circuit breaker.
- MCC incoming feeder protection at large motor control centres at Aramco and SABIC process plants, combining incomer isolation and short-circuit protection.
- Distribution board incomer protection at commercial and government buildings, where 400–800 A NH size 1 and 2 fuse switches protect the main circuit from upstream fault currents.
- Generator output cable protection at hospitals, data centres, and critical infrastructure diesel generators, where NH gG fuse links protect output cables before the generator excitation responds.
- Welding transformer and arc furnace feeder protection at steel fabrication facilities, where NH aM motor-duty fuse links handle high inrush currents without nuisance operation.
- Water utility sub-distribution feeder protection at NWC remote facilities, where combined fuse-switch function reduces maintenance exposure to live circuits during routine fuse inspection.
