Product catalog summary

Company Overview: Woertz AG, a family-owned business established in 1928, is based in Muttenz, Switzerland, with a branch in Hölstein. The company employs approximately 220 people and specializes in manufacturing circuitry accessories, installation systems, and electronic control systems. Woertz is ISO 9001 and ISO 14001 certified, focusing on security, user-friendliness, and ease of handling in their products.

Product Range: Woertz offers a variety of products including terminals, junction boxes, grounding products, surge protection devices, flat cable installation systems, floor ducts, electronic modules, and interfaces. Circuitry accessories and electronic control systems are produced at the headquarters, while duct and double floor systems are manufactured in Hölstein.

Insulating Materials: The insulating bodies of terminals are made from polyamide 66, known for its hardness, rigidity, scuff resistance, and thermal endurance. It is self-extinguishing, halogen-free, and approved by leading certification institutions, capable of withstanding temperatures up to 100°C and reinforced with fiberglass for higher temperature applications.

Connection Types: Woertz provides various terminal types, including screw connections with or without springs, and branching terminals for through conductors. These terminals are corrosion-resistant and suitable for marine systems and hazardous locations.

Nominal Cross-Section: Terminals can connect multiple conductors of the terminal's nominal cross-section, accommodating solid, rigid stranded, and flexible conductors.

Earthing and PEN Conductor Subdivision: The document emphasizes the subdivision of the PEN conductor in distribution systems, using neutral disconnecting terminals and bare earthing terminals to ensure safety and compliance with electrical standards.

Terminal Series Overview: The catalog includes various terminal series for mounting rails according to EN 60715 TH 35, such as basic terminals, enclosed and bare earthing terminals, disconnecting terminals, and fuse terminals, each designed to meet specific demands and heavy-duty applications.

Technical Specifications Overview:

Voltage and Current Ratings: Terminal blocks have voltage ratings from 250V to 800V and current ratings from 6.3A to 269A, depending on type and configuration.
Connecting Capacity: Terminals support wire sizes from 0.5 mm² to 120 mm², accommodating both solid and stranded conductors.
Clamping Mechanism: Clamping screws are made of nickel-plated brass, with options for slotted and socket screws. Clamping torque values are provided for electric screwdrivers.
Material Composition: Components are constructed from materials such as nickel-plated brass, stainless steel, and PA 66 for insulation.

Accessories and Marking:

Marking Accessories: Various labeling options are available to ensure clear identification of terminals.
End Barriers and Stoppers: Provided to ensure safety and proper termination of connections.

Special Features and Recommendations:

Disconnecting Terminals: Include knife disconnecting mechanisms for safe operation with additional springs to prevent loosening.
Fuse Terminals: Options with and without LED indicators for fuse status, supporting fuses up to 6.3A.
Branching Terminals: Designed for main and branch connections, including sliding covers and available in various sizes and ratings.
Safety Precautions: Advises against handling plugs or knives when live and considering heat generation in fuse terminals during installations.

Installation and Usage:

Connection Instructions: Detailed steps for connecting conductors, including unscrewing clamping screws and inserting conductors before securing them.
Protection Against Contact: Accessories available to ensure safe handling and operation of terminals.

The insulating body of our terminals is made of polyamide 66. Even if this polyamide is subjected to a constant temperature of 100C, it fulfills the electri-cal, mechanical and chemical properties required in terminals. The typical features of polyamide 66 are hardness, rigidity, scuff resistance and thermal en-durance.Fuse terminals and fuse plugs, where constant temperatures of over 100аC can occur, are made of polyamide 66 reinforced with fibreglass.Polyamide 66 is hardly combustible, self-extinguishing and halogen-free (when a fire breaks out, there cant be any emanation of toxic gas combustion,which,...
