Overview

Energy Meter and Network Protection AC 85–290 V 80 A 3 Phase 4 Wires DIN Rail KWS-306 without Wi-Fi Overvoltage Undervoltage Overload

This device combines precise consumption measurement and comprehensive protection of three-phase installations in one compact body for mounting on a DIN rail. The colour LCD VA display clearly shows voltage, current, power, frequency, and temperature, facilitating quick checks of network status. The range of AC 85–290 V and current up to 80 A per phase covers a wide variety of applications in homes, operations, and distribution boards. The unit operates in 3-phase 4-wire configuration and retains data even after a power failure thanks to its memory. The without Wi-Fi variant is ideal where simplicity, stability, and maximum reliability without network connection are required.

  • Comprehensive protections: overvoltage, undervoltage, overcurrent, overload, overheating, voltage and current imbalance – protects devices and installations.
  • Precise measurement: voltage, current, power, power factor, frequency 50–60 Hz, energy up to 99 999 999 kWh.
  • User functions: timer, screen saver settings, energy counter and timer reset, memory after power failure.
  • Tool-free installation: quick mounting on standard DIN rail, clear terminals A/B/C/N and input for NTC.
  • Wide applications: flats, rental properties, offices, hotels, low/high voltage distribution boards, production lines, warehouses, display cases, and shelves.
  • Parameters: voltage range AC 85–290 V, current 0–80 A, power 0–23 kW, ambient temperature −20 to 150 °C, power factor 0.00–1.00 PF.
  • Package contents: 1× energy meter KWS-306

With its clear display and sensitive protections, you gain immediate insight into the load and status of each phase, along with timely disconnection in dangerous conditions. The design with a low-power magnetic relay enhances switching reliability and longevity. The device is suitable for modernising distribution boards as well as new installations where safety, monitoring, and easy installation are emphasised. If you prefer a purely local solution without network connection, the without Wi-Fi variant is the ideal choice. KWS-306 will help you save costs, protect devices, and maintain operation without interruptions.
