The T-piece 79309.000 from Erco-Leuchten is a component for 3-phase power rails, made of white plastic. It serves as a branching element in high-voltage power rail systems to distribute electrical energy to multiple consumers or luminaires. The design allows both power input and through-wiring, enabling flexible integration into existing rail systems. The protective conductor position is located on the left, which must be considered during power supply planning and compliance with electrical safety regulations.

T-piece
The T-piece is specifically designed for 3-phase power rails and enables branching of the power supply within a rail system. It is made of white plastic, ensuring good visibility and clean optical integration into technical installations. The connection is made via the integrated power rail plug connection, designed for secure and reliable power transmission.

Functions and equipment in detail
The component supports the input of electrical energy, allowing it to function as an entry point in a power rail system. At the same time, it enables through-wiring, allowing power to be transmitted further through the T-piece without interrupting the power supply. The left-side positioning of the protective conductor is a fixed technical parameter that must be considered during installation and when connecting to other components to ensure correct earthing.

Technology explained clearly
The power rail component is designed for high-voltage applications and complies with standards ENEC10 and VDE. These certifications guarantee the electrical safety and reliability of the component under operating conditions. The use of plastic as material ensures high insulation performance and protects against unintended current paths. The design of the T-piece allows for easy installation into existing rail systems, with electrical connections made via integrated plug contacts.

Compatibility and accessories
The T-piece 79309.000 is intended for 3-phase power rails and can be combined with other components of the Erco-Leuchten power rail system. It is compatible with corresponding power rail profiles and enables integration of luminaires, sockets, or other consumers supplied via the power rail system. Use within a closed system ensures proper power distribution and a safe electrical connection.

Installation and mounting
Mounting is done by simply plugging into the power rail. The electrical connection is automatically established via the integrated contacts. During installation, correct alignment of the protective conductor, positioned on the left, must be ensured. Compliance with electrical standards and proper installation are crucial for the safety and functionality of the entire power rail system.

Advantages in operation
The T-piece enables flexible and scalable power distribution in high-voltage installations. The through-wiring function reduces the number of required connection components and simplifies installation. Certification according to ENEC10 and VDE ensures reliability and compliance with safety standards. The use of white plastic provides clear visual identification and facilitates system maintenance and inspection.
