3-phase power rail

The Erco-Leuchten power rail type 78341.000 is a high-voltage power rail system made of aluminium profile, powder-coated in white (RAL9002), with a length of 1000 mm. The system is designed for use in professional lighting installations, particularly in conjunction with DALI control systems or as a 3-phase power rail. It serves as a distribution element for electrical energy and data transmission in modern lighting concepts, where power supply and control are carried out via a common rail system.

Applications

The power rail is intended for use in indoor environments, particularly in office buildings, administrative buildings, retail spaces, and other areas with high lighting density. It enables the flexible and modular arrangement of luminaires and other electrical devices along the rail. The construction allows for use as a DALI control rail as well as a 3-phase power rail, making it suitable for various electrical installation configurations.

Functions and Equipment in Detail

The aluminium profile features a mounting surface with punch-out mounting points spaced at 0.4 metre intervals, enabling flexible and quick attachment of luminaires and accessories. The rail integrates four insulated copper conductors as well as a crimped protective conductor, ensuring electrical safety. When used as a DALI power rail, it provides a circuit with a rated current of 16 A, supplemented by two conductors for connection to the DALI data line. This enables decentralised control of luminaires via the DALI protocol. As a 3-phase power rail, it offers three separately switchable circuits, each with a rated current of 16 A, allowing load distribution across three phases.

Technology Explained Simply

The power rail is approved according to IEC 60570 (equivalent to EN 60570/VDE 0711 part 300), confirming compliance with international standards for power rail systems. The use of copper conductors ensures high electrical conductivity and minimises losses. The crimped protective conductor ensures safe earthing of connected devices. DALI integration enables intelligent lighting control, allowing luminaires to be dimmed and controlled individually or in groups. The 3-phase function is particularly useful for larger installations, as it enables even load distribution across phases and thus optimises network load.

Compatibility and Accessories

The system is part of the ERCO power rail system and can be combined with compatible luminaires, sockets, switches, and other components from the same system. The power rail is designed for use with DALI control systems, with the data line connected via the integrated conductors. The 3-phase function requires a corresponding network supply and is suitable for installations with higher power consumption.

Installation and Mounting

Mounting is carried out on the designated mounting surface, where the punch-out mounting points enable easy and secure fastening. The rail is mounted on the ceiling or wall, depending on the requirements of the lighting installation. Electrical connections are made via the integrated conductors, with wiring to be carried out in accordance with applicable standards and regulations. Installation requires knowledge of electrical standards and compliance with safety regulations.

Operational Advantages

The power rail offers a flexible and scalable solution for lighting technology. The integrated DALI control enables intelligent and energy-efficient use of lighting. The 3-phase function ensures optimised load distribution and reduces the load on individual phases. The powder-coated white surface (RAL9002) provides a clean and attractive appearance, fitting well in modern indoor spaces. Approval according to IEC 60570 ensures the reliability and safety of the system.
