Semiconductors are electronic components extremely sensible to overloads and short-circuit, therefore they cannot be protected with general purpose fuse-links. For this reason there are ultra rapid fuse-links for this specific purpose, with very fast melting characteristics, low let-through energy values (I2t) and adequate selective coordination with protection devices upstream.
gPV Fuse links for photovoltaic installations from DF Electric have been developed to offer a compact, safety and economic protection solution in photovoltaic installations where, due to the increase of the power and technologic evolution, no-load voltages up to 1000V DC are reached. Also meet the requirements for instruments (multimeters) and traction equipment auxiliary circuits.
NH fuse links gG and aM class with high breaking capacity, for use as general protection against overloads and short circuits, intended as protection for cables, power lines and equipment with rated voltage up to 500V.
Compact versions in low rated currents of every size. Fusing indicator in the top of the fuse link.
Modular fuse holders for cylindrical fuse links size 14x51 & 22x58
according IEC 60269 standard.
Compact design, with reduced dimensions. Ventilation zones optimized for a better heat dissipation. Manufactured with a high quality materials.
Available in a extended range of different versions with fuse indicator, with microswitch, 690V, 24 V DC, Microswitch FUSING+PRE-BREAKING+FUSE LINK DETECTION.
DF ELECTRIC launch a new photovoltaic modular fuse holders for photovoltaic applications.
The first feature that this news products offers, is the assigned 1000 V DC voltages. They have been developed to offer a compact, safety and economic protection solution in photovoltaic installations where due to the increase of the power and technologic evolution, no-load voltages up to 1000V DC.
Single-phase safety transformers intended to supply spotlights in swimming-pools, garden ponds, ornamental fountains and moist locations, where for safety reasons it is necessary to supply with safety extra low voltage (SELV). It has several taps in the primary winding in order to compensate for the voltage drop in the transformer-spotlight line conductors and thus gets an adequate brightness in every spotlight.
