## Long description

The Legrand 412043 is a professional 3-phase energy meter engineered for precise monitoring of electricity consumption in industrial and commercial environments. This device utilizes current transformers (CT) for measurement, supporting a 5A input to ensure accurate data collection across complex electrical networks. Equipped with dual-tariff functionality and an integrated RS485 communication interface, it allows for seamless connectivity with energy management systems, enabling efficient remote monitoring and data logging.
Advantages
This energy meter offers high precision in power measurement, making it an essential tool for facility managers and engineers aiming to optimize energy efficiency. The inclusion of an RS485 interface facilitates easy integration into existing building automation or energy management infrastructures, allowing for real-time data transmission. Its dual-tariff capability provides flexibility for users operating under different electricity pricing structures, while the CT-based measurement ensures reliable performance even in high-load electrical installations.
Suitable for
Industrial manufacturing facilities
Commercial office buildings
Data centers requiring power monitoring
Multi-tenant commercial properties
This device may not be suitable for residential applications where direct-connected meters are standard, as it specifically requires external current transformers for operation. It is also not intended for use in environments exceeding its specified voltage or current ratings, nor is it suitable for installations where communication protocols other than RS485 are required without additional converters.
Key specifications
Measurement type: 3-phase with current transformers (CT)
Input current: 5A
Communication: RS485 interface
Functionality: Dual-tariff
Dimensions: 80 mm width, 95 mm depth, 75 mm height
Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is designed for DIN-rail mounting within a distribution board. Once mounted, the current transformers must be correctly wired to the meter inputs, and the RS485 communication lines should be connected to the central monitoring system. Configuration of the meter settings, such as CT ratios and communication addresses, should be completed via the device interface or compatible software.
What to consider before purchase
Compatibility with existing current transformers
Availability of an RS485-capable monitoring system
Space requirements within the electrical distribution cabinet
Need for dual-tariff billing support
For optimal performance and accurate data logging, ensure that the current transformers are correctly sized for the load and that the RS485 bus is properly terminated to prevent signal interference.
