Indirect measurement system ZK1-1Pp/F R2G51-0001-001

Indirect measurement system – a solid foundation for safe and precise energy reading

This indirect measurement system, compliant with the ENEA standard, is a comprehensive solution for connecting a single installation. Designed for reliability and ease of installation, it works well both in new installations and during the modernization of existing ones. The construction ensures safe and accurate energy consumption measurements, and the solid workmanship guarantees long-term operation.

Functionality and construction

The system consists of a number of key elements providing full functionality: a strip fuse disconnect switch (size 2, single-pole with "V"-type terminals), a strip isolating disconnect switch (size 2, three-pole with "V"-type terminals), plastic cable mounting brackets, and a 230V/16A socket with an overcurrent switch (characteristic B). The busbars are made of tinned copper (40 mm x 5 mm), and the PEN busbar has two "V"-shaped cable terminals bent in the shape of a C. In the cable compartment there is a tinned copper busbar (40 mm x 5 mm) prepared for mounting transducers. Connections from the transducers to the meter are made with a copper wire with a cross-section of 2.5 mm². In the meter compartment, a measuring strip compliant with the ENEA standard and a TL-3f meter panel have been mounted.

• ENEA standard compliance: Guarantee of compatibility with the existing energy infrastructure.
• Safety: Equipped with fuse disconnect switches and an overcurrent switch to protect against overloads and short circuits.
• Solid construction: Housing with a wall thickness of ≥3.5 mm and flammability class V0 provide high resistance to mechanical damage and fire.
• Easy installation: Cable mounting brackets and prepared places for transducers facilitate installation.
• Prepared for expansion: A gap left in the cable compartment allows for easy mounting of current transformers in the future.

Parameters and dimensions

The measurement system has dimensions of 800 mm (width) x 1690 mm (height) x 250 mm (depth). The IP44 protection class provides protection against splashing water and solid objects larger than 1mm. It is made of steel, which guarantees durability and corrosion resistance. The model is intended for domestic use (eHZ energy meter).
