KWS-302WF Energy Meter WiFi 63A

The KWS 302WF is a DIN rail-mounted Tuya WiFi smart energy meter that packs eight electrical measurement parameters into a single compact, colour-display unit. Measuring voltage, current, active power, energy consumption (kWh), timing, temperature, frequency, and power factor simultaneously, it gives homeowners, landlords, facility managers, and electricians a comprehensive real-time view of electricity usage from anywhere via the Tuya Smart or Smart Life app.

The built-in relay switch allows remote on/off control, and programmable protection thresholds for over-voltage, under-voltage, over-current, over-power, and over-temperature automatically disconnect the load when limits are exceeded safeguarding connected appliances and wiring.

An external NTC temperature probe allows monitoring of panel or equipment temperature alongside electrical parameters. Power-off memory retains kWh and protection settings after power loss. Installation is tool-free via standard 35mm DIN rail snap-on mounting, making it suitable for distribution cabinets, rental apartments, commercial premises, and home consumer units.
