The transition and fuse box EKM-1271-1D2-5X16 from Tyco Flow Control Thermal Controls GmbH is a component specifically designed for installation in light poles, serving electrical connection and protection purposes. It functions as a switching and distribution element within the pole structure, enabling secure connection and wiring technology for cables and fuses. The housing is made of impact-resistant plastic, ensuring high mechanical stability and resistance against external influences. The design is intended for use in outdoor installations, with protection class IP 43 providing protection against splashing water and dust, although not suitable for permanent immersion or continuous splashing water exposure outdoors.

Applications
This box is primarily intended for installation in light poles, especially those with an inner diameter of at least 90 mm. The required door opening in the pole must be at least 80 mm (width) × 210 mm (height) to allow for installation and maintenance. It is typically used in the electrical distribution area within the pole to ensure secure and structured power supply for lighting elements. The product is used in public or industrial outdoor installations where reliable and maintainable electrical installations are required.

Functions and Equipment in Detail
The EKM-1271-1D2-5X16 features a fuse socket complying with standard E27, designed for mounting a fuse. The integrated unistrut clamp allows for secure fastening of cables and wires. The conductor cross-section specification indicates that the box is designed for one or two cables with a cross-section up to 5 x 16 mm², supporting a wide range of connection configurations. The housing dimensions are 202 mm (length) × 76 mm (width) × 83 mm (height), representing a compact yet sufficiently sized design for use in light poles.

Technology Explained Simply
Protection class IP 43 means the device is protected against splashing water from any direction and against ingress of foreign objects such as dust. This makes the box suitable for outdoor use, provided there is no direct, continuous water exposure or immersion conditions. The impact-resistant plastic housing offers mechanical protection and is resistant to mechanical stresses that may occur during installation or maintenance. The unistrut clamp ensures secure and durable fastening of electrical wires, guaranteeing a stable connection.

Compatibility and Accessories
The box is specifically designed for light poles with an inner diameter of at least 90 mm. The required door opening in the pole (minimum 80x210 mm) must be present to enable installation. It is used in combination with electrical cables and fuses, with the E27 fuse socket being the standard configuration.

Installation and Mounting
Mounting is done by inserting the unit into the light pole, using the designated door opening (minimum 80x210 mm). Electrical connections are made via the unistrut clamp, taking into account the maximum conductor cross-sections (up to 5 x 16 mm²). Installation requires basic knowledge of electrical work and should be carried out by qualified professionals.

Operational Advantages
The box provides a compact and robust solution for electrical distribution in light poles. The integrated fuse enables simple and secure protection of the power supply. The use of impact-resistant plastic and protection class IP 43 ensures high reliability under outdoor conditions. Clear dimensions and designated connection options simplify installation and maintenance, thereby increasing operational safety and the service life of the installation. Standardization of the fuse socket (E27) allows for the use of common fuses and facilitates replacement during maintenance work.
