DF Electric products

gG Class Cylindrical fuse links for use as general protection against overloads and short circuits, intended as protection of cables, power lines and equipment. Made of ceramic tube with high withstand to internal pressure and thermal shock, that allow a high breaking capacity in a reduced physical space. The melting elements are specially designed in order to avoid aging and thus maintain unalterable the electrical characteristics. Contact caps are made of silver plated copper.

Cylindrical fuse links aM class are intended for short circuit protection in motors, transformer and other load with high inrush currents. 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 as a thermal switch. Made of ceramic tube with high withstand to internal pressure and thermal shock, that allow a high breaking capacity in a reduced physical space. The melting elements are silver plated in order to avoid the aging and thus keep unalterable the electric characteristics. Contacts caps are made of silver plated copper. Versions available with fusing indicator or with striker for use in fuse holders with microswitch.

Microswitch for NH fuse links with top indicator. Presence and fusing. Manual assembly. Compact design. Two positions. Manufactured with plastic materials with high temperature resistance and self-extinguishable.

Intended for protection of power lines and equipment. 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 120 kA at 500V and 80kA at 690V. 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.

Intended for short circuit protection in motors and transformers. 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.
