Product Overview


Our Three Phase Four Wire Din Rail Digital Energy Meter is a professional 4-module rail-mounted power measuring instrument, engineered for high-precision electrical energy monitoring and control in industrial and commercial electrical systems. As a core compact digital energy meter for electrical cabinets, it complies with international standards like DIN EN5002 and is designed for 35mm standard DIN rail installation, delivering a perfect combination of easy operation and stable performance. This 3 phase din rail kWh meter features a space-saving structure, making it ideal for limited installation spaces such as distribution boxes and control cabinets, and eliminates the need for dedicated power monitoring rooms—directly cutting down installation and time costs for clients with bulk deployment demands.


Key Features & Core Advantages


Standard DIN Rail Mounting & Hassle-Free Installation

The meter adopts DIN rail mounted design for electrical systems with top and bottom dual connection modes, fitting 35mm standard DIN rails universally used in global industrial projects. The standardized installation interface ensures fast assembly and stable fixation, suitable for integrated deployment in various electrical systems, and greatly improves on-site construction efficiency for engineering and procurement teams.


Class 1.0 High Accuracy Energy Measurement

As a high accuracy 3 phase digital electricity meter, it reaches Class 1.0 accuracy grade, accurately measuring active energy in 50Hz/60Hz three-phase AC grids with a starting current of only 0.04%Ib. It supports multiple basic current specifications (5A/10A/15A/20A/30A) and a maximum current of 100A, meeting the precise metering needs of different load scenarios in industrial and commercial sites.


Compact & Lightweight Industrial Design

With a compact size of 76mm(W)*76mm(D)*89mm(H) and a net weight of just 0.38kg, this lightweight din rail energy meter can be flexibly installed in narrow electrical enclosures. Its modular 4-module structure ensures easy integration with existing electrical systems, avoiding space waste in large-scale project deployments.


Reliable Performance in Diverse Environments

Powered by advanced microelectronic technology and imported dedicated large-scale integrated circuits, the meter maintains stable and accurate operation in a wide temperature range of -25℃~70℃. It features high anti-interference ability and long service life, making it a durable 3 phase energy meter for industrial sites that adapts to complex working environments of factories, ports and airports.
