The transition and fuse box EKM-2050-3D1-5S/U from Tyco Flow Control Thermal Controls GmbH is an electrical distribution element designed for installation in light poles. It complies with standards DIN / VDE 0660 T. 505 and bears the VDE mark, confirming compliance with relevant safety and functional requirements. The SK version is specifically designed for installation in poles with an inner diameter of at least 89 mm. The door size is at least 85 x 270 mm, enabling access to internal components. The box serves as a transition point and fuse element for electrical lines in outdoor installations, particularly in lighting systems for streets, parks, or industrial facilities.

Applications

The EKM-2050-3D1-5S/U is designed for use in outdoor installations where safe and weather-resistant distribution of electrical power is required. It is typically integrated into light poles to ensure power supply for multiple luminaires or electrical loads. The construction allows flexible adaptation to various network configurations, making it universally applicable in different electrical installations. The protection rating IP 54 ensures protection against dust and splashing water, making it suitable for outdoor use.

Functions and Equipment in Detail

The box features a compact installation block consisting of three fuse sockets with a rated current of 16 A and designation D01-E14. It includes three screw caps E14 to securely fix the fuses. Power distribution is achieved via five sliding terminals designed for network configuration L1, L2, L3, N, and PE(N). The rail connection consists of nickel-plated brass rails, ensuring a reliable electrical connection. The PE and N outlet terminals are fully insulated, providing additional protection against contact and short-circuit.

Technology Explained Simply

The protection rating IP 54 means the box is protected against dust and splashing water, making it suitable for outdoor use. Protection class II ensures the box can be operated safely without additional protective measures such as grounding or protective conductor. The transparent lid with snap closure allows easy inspection of internal components, while the shock protection ensures operator safety. The wire branching space of 60 mm provides sufficient room for cable connections and installation of fuse elements.

Compatibility and Accessories

The box is designed for installation in poles with an inner diameter of at least 89 mm. The access opening allows installation of two cables up to 4 x 25 mm² or three cables up to 5 x 16 mm², with a cable tie used for securing. On the outlet side, two outlet ferrules are integrated to enable connection to luminaires. Two luminaire connection cables can optionally be mounted parallel to the access cable downward, enabling flexible installation in various configurations.

Installation and Mounting

Mounting is done by installing the box into the light pole, with a minimum inner pole diameter of 89 mm. Cables are introduced through the designated access openings and connected to the sliding terminals. Fuses are inserted into the sockets, with screw caps ensuring secure fastening. The lid is closed using the snap closure, protecting the box from external influences.

Operational Advantages

The EKM-2050-3D1-5S/U offers a compact and safe solution for power distribution in outdoor installations. Its universal applicability for various network configurations and flexible mounting options for luminaire connection cables increase adaptability to different requirements. The use of nickel-plated brass rails and fully insulated terminals ensures a reliable and long-lasting electrical connection. Protection rating IP 54 and protection class II guarantee safe outdoor operation without additional protective measures.
