NH FUSE LINKS

gG

gG NH fuse links

Knife type (NH) fuse-links gG class for general use, with top indicator. These high breaking capacity fuse-links are intended for protection of power lines and equipment, against overloads and short-circuits with rated voltages up to 500V AC (+10%) and 690V AC(+5%). The rated breaking capacity is 80 kA at 690V or 120 kA at 500V. The range comprises fuse-links from size NH000 up to NH4, with rated currents from 2A up to 1250A. Compact versions in low rated currents of every size. Manufactured with ceramic body with high withstand to internal pressure and thermal shock, that allows a high breaking capacity. Knife contacts are made of silver plated copper or brass. They are manufactured according to IEC/EN60269 and VDE0636 Standards and comply with RoHS directive.

aM NH fuse links

Knife type (NH) fuse-links aM class for motor protection, with top indicator. These high breaking capacity fuse-links are intended for short circuit protection in motors, transformer and other load with high inrush currents, with rated voltages up to 500V AC (+10%) and 690V AC (+5%). The rated breaking capacity is 80 kA at 690V or 120 kA at 500V. Excellent protection of switchgear (contactor, thermal switch) due to the good current limiting capability and low I2t values. These fuse links must be associated to an overload device protection (thermal switch). The range comprises fuse-links from size NH000 up to NH4, with rated currents from 6A up to 1250A. Compact versions in low rated currents of every size. Manufactured with ceramic body with high withstand to internal pressure and thermal shock, that allows a high breaking capacity. Melting elements are silver plated in order to avoid the aging and thus keep unalterable the electric characteristics. Knife contacts are made of silver plated copper or brass. They are manufactured according to IEC/EN60269 and VDE0636 Standards and comply with RoHS directive.

NH FUSE BASES

ST

Fuse bases for NH fuse links. For mounting on DIN/EN rail or with screw fixing. Single-phase or three-pole type. Connection by screws, fixed nut or clamps. Wide range of accessories (contact covers, fuse link covers, partition walls) that enables IP20 protection index. Multi-pole units can be made with connection accessories. NH ST fuse bases are made of self-extinguishable materials and have silver plated copper contacts. There are two contact styles, one of them with double spring in order to obtain an optimum operation. Manufactured according IEC, EN and DIN standards.

CR

Fuse bases for NH fuse links. For screw fixing. Single-phase or three-pole type. Connection by screws. NH CR fuse bases are made of ceramics and have silver plated copper contacts. There are two contact styles, one of them with double spring in order to obtain an optimum operation. Manufactured according IEC, EN and DIN standards.

SECTIONABLE NEUTRAL

Neutral bases for mounting on DIN/EN rail or with screw fixing. Connection by screws or clamps. NH00 and NH0 can be mounted in NH ST fuse bases with connection accessories. Made of self-extinguishable materials and have silver plated copper contacts. Can be mounted in NH ST fuse bases with connection accessories. All the materials are according to the European Directive 2002/95/EC RoHS (Restriction of the use of certain hazardous substances in electrical material). Manufactured according IEC, EN, VDE and DIN standards. 

FUSE SWITCH DISCONNECTORS

Three-phase fuse switch disconnectors for NH fuse-links. Available from size 000 to size 3 for board fixing and a mode size 00 for mounting on 60 mm busbar system. They provide IP20 protection against contacts and are manufactured in self-extinguishable materials.
