The fuse box type EKM-2050-2D1-5S/U-2SA-E1 from Tyco Flow Control Thermal Controls GmbH is a single-phase switch box designed for use in electrical installations, particularly in areas where safe and reliable power supply with integrated surge protection is required. It is designed for mounting on light poles or similar outdoor installations, where it serves as a protection and distribution element for electrical loads. The box allows for the installation of two fuses and is equipped with five sliding terminals, ensuring flexible and secure connection of the cables. Two surge protection modules are integrated to protect the installation from transient overvoltages, which may occur due to lightning strikes or switching operations.

Applications

The fuse box is intended for use in outdoor installations, particularly in connection with light poles, where it functions as a central distribution unit. It is suitable for applications requiring safe power distribution with integrated surge protection, such as street lighting systems, industrial installations, or public facilities. The single-phase design makes it especially suitable for installations operated on a single phase, which is common in many lighting systems.

Functions and Equipment in Detail

The box provides space for two fuses, which protect the electrical loads. The five sliding terminals allow for quick and secure connection of supply cables, ensuring a mechanically stable connection. The integrated surge protection modules offer additional protection against short-term voltage spikes that could damage electrical components. The construction allows for both parallel and series connection of the fuses, depending on the requirements of the installation. An E-strap with an M8 screw is integrated, enabling secure mounting of the box to a pole or other structure.

Technology Explained Simply

The integrated surge protection modules respond to sudden voltage spikes by diverting them in a short-circuit manner, protecting the equipment connected downstream. The sliding terminals are designed to ensure a firm and correct connection of the cables without requiring additional tools for installation. The single-phase design means the box is designed for a single voltage phase, which is common in many lighting installations. The E-strap with the M8 screw serves mechanical fixation, ensuring the box remains securely attached to the pole even under external loads such as wind or vibrations.

Compatibility and Accessories

The fuse box is designed for outdoor installations and can be used in combination with other components from Tyco or compatible manufacturers, particularly in lighting systems. The integrated surge protection modules are suitable for use in electrical installations requiring surge protection.

Mounting and Installation

Mounting is carried out on a suitable pole or other supporting structure, using the integrated E-strap with the M8 screw for fastening. The sliding terminals allow for easy and secure connection of the cables, with no additional tools required. The fuses are inserted into the designated holders, and the surge protection modules are already integrated into the box. Installation must be carried out in accordance with applicable electrical standards and regulations.

Operational Advantages

The fuse box offers a compact and reliable solution for power distribution in outdoor installations. The integrated surge protection modules increase the safety of the installation by protecting against transient overvoltages. The sliding terminals enable quick and secure installation, and the E-strap with the M8 screw ensures stable fixation. The single-phase design makes it particularly suitable for lighting installations, where simple and secure power distribution is required. The combination of fuses and surge protection in a single housing reduces the number of required components and simplifies installation and maintenance.
