Smart energy sensor, 3P+N, 63A, Modbus RS485Features:The smart energy sensor is an advanced device designed to effectively and accurately track energy consumption in three-phase systems with a neutral wire (3P+N). It can also be applied to a single-phase system.More suitable for industrial, commercial or larger residential installations. It can monitor multiple phases or individual circuits simultaneously.Advanced energy monitoring: real-time measurements of voltage, current, power, electricity consumption and frequency.Current measurement up to 63A ensures accurate monitoring of energy consumption.The device can analyze phase balance in three-phase systems. It has additional functions that allow you to monitor and compare the parameters of multiple phases or circuits.Modbus RTU communication model is used, compatible with industrial control systems. Ensures stable and fast communication in large facilities.This meter can be installed in more flexible electrical system configurations, it does not take up space on a DIN rail. It can be installed in an electrical circuit after a main circuit breaker, fuse or distribution panel, allowing it to monitor the energy consumption of specific electrical circuits or devices.The energy sensor is suitable for industrial, commercial or larger residential installations.Notes: Do not install this device before a circuit breaker or fuse, as the device is not intended for protection and may be damaged by electrical faults.Installing this device downstream of control devices such as contactors, variable frequency drive or motor starters is forbidden. This may cause voltage pulses, harmonics or instantaneous current surges that would damage the device. Do not use where the current exceeds the nominal limit of the device 63A.The device must be installed in a dry place or using special protective boxes if there is a risk of moisture.Technical specifications: Max. current (Imax): 63 A (3P+N).Operating voltage: 208~415V AC.Frequency: 50/60 Hz.Nominal insulation voltage (Ui): 400V.Energy measurement accuracy: 1%; Class 1.Operating consumption: 0.7W.Nominal impulse withstand voltage (Uimp): 4 kV.Overvoltage category: III.Communication type: Modbus RS485.Reload button: yes.Indicator light: yes.Installation: downstream.Protection class: IP20.Operating temperature: -25°C~+60°C.Measuring cavity diameter 9.8mm.Dimensions: 46.8x52.8x21.3mm.Warranty: 24 months.
