Connection and measurement kit ZK2a-1P (TNC, 25A) P4019-1-2-25L

Metering connection set ZK2a-1P (TNC, 25A) is a complete solution for connecting a single installation, compliant with the Tauron standard. It is a self-supporting cable and metering connection, suitable for both new and modernized facilities. The set's design ensures a safe and reliable connection and enables energy consumption measurement.

Complete equipment and solid construction

The set is equipped with everything necessary for the proper functioning of the metering point. The cable compartment contains busbars, two 400A strip fuse disconnectors with V-type terminals, and a PEN busbar. The metering compartment includes a housing with a built-in 00-size fuse disconnector, a power limiter (25A), a TL-3f meter panel, and 16mm² cross-section cables. The housing is made of steel with a wall thickness of at least 3.5 mm and has a flammability class of V0 – guaranteeing high fire resistance and safety.

Safety and protection

The ZK2a-1P set provides not only convenient installation and use but, above all, the safety of the electrical installation. The applied protections protect the circuit against overload and short circuit. The IP44 protection class guarantees resistance to the ingress of solids and water, allowing installation both indoors and outdoors – although protection from direct atmospheric influences is recommended.

• Equipped with 400A strip fuse disconnectors with V-type terminals – ensuring reliable disconnection of the load in case of failure.
• PEN busbar – dedicated to connecting protective and neutral conductors, increasing safety.
• 25A power limiter – protects the meter and installation from overvoltage.
• Housing with a thickness of ≥3.5 mm and flammability class V0 – provides high mechanical and fire resistance.
• Protection class IP44 – resistance to the ingress of solids and water.

The dimensions of the set are 665 mm wide, 1690 mm high, and 320 mm deep. This makes it easy to install and integrate with existing electrical infrastructure.
