• Regardless of cold, heat, dust, water or pressure/tensile/impact loads in the most diverse conditions under extreme use.

DIN Rails & Accessories

• This series of DIN rail (mounting rails) is for industrial application according to the standard EN 60715 with third generation of Cr3 +Passivation (TDR3-Series) for improved corrosion resistance and SST stability of 350Hrs.
• DIN rails are designed in accordance with the European standard EN 60715 using state of the art production processes to ensure high dimensional accuracy, restricted tolerances and outstanding surface tempering. The DIN rails are available in standard lengths of 1M and 2M or to required lengths* with or without perforation.
• We also offer universal DIN rail cutter. In accordance with IEC 60 947-7-2, DIN rail made of steel may be used as equipotential busbar (PE function), but without PEN function. Our entire range of DIN rails are RoHS & CE compliant.

Wiring Duct (PVC Channel)

Trinity Touch wiring ducts is the product, available in wide range to accommodate wires and cables for the smallest wall mounted panel to larger integrated systems.

Halogen Free Wiring Ducts

• When PVC or other traditional plastics ignite in a fire, they emit corrosive & toxic gases like chlorine. Moreover, these are soluble in moisture, forming hydrochloric acid, which destroy electronics, semiconductors and intrinsic electrical circuits.
• While smoke travels containing toxic element, it can be fatally hazardous to humans if they cannot escape from that area.
• Toxic fumes are not only a serious health risk but also cause serious damage and problems to crucial machinery and intrinsic devices. Halogen free wires and cables are already compulsory in many areas as they are safer.
• In the same way, HF wiring duct is most important within enclosed spaces where the exits are limited such as public transport, hospitals, malls etc.
• What is the use of halogen free cables if the wiring ducts contain dangerous material? For example: Hospitals, Airport Terminals, Concert Halls, Sports Stadiums, Railway Stations, Ships, Offshore Oil and Gas platforms, Multistory Buildings and Nuclear Power.

Electrical Protection

Our fuse is an electrical safety device that has the capability to protect an electric circuit from excessive electric current. It is designed to allow current through the circuit, but in the event that the current exceeds some maximum value it will open, severing the circuit.

Flexible Conduits & Accessories

• Flexible conduit is commonly used for the protection and containment of vulnerable electrical cables, wiring and fiber optics. It is an extremely effective form of cable management, available in a variety of systems, which can cope with a diverse range of environmental factors and operating conditions.
• With a comprehensive stock holding we strive to deliver service excellence to meet our customer demands faster, ensuring you can count on us.
