If not, does anyone have a suggestion for one that can?** A: No, this meter can not run in reverse. **Q: Does this measure rms or average ac?** A: This energy meter measures rms. **Q: This seller is selling a device that cannot accurately measure power in a us based household. only one "hot" lead is being measured and a house panel** A: So use two and add them together. **Q: How many power meters do i need to monitor: phase 1+ n (110v), phase 2 + n (110v), and phase 1 + phase 2 (220v)?** A: hi it depends on your requirement. You can only use one meter to monitor one of the phase + n . Or you can use three meters to monitor each phase + n . ## Customer Reviews ### ⭐⭐⭐⭐⭐ Medidor de calidad *by on Reviewed in Spain 9 August 2026* Despues de 12 años de uso, ha dejado de funcionar mi medidor Ketotek, me mide parcialmente por que un condensador ha calentado el cable plano qye lleva en su interior, tenia el sencillo, sin contador.Ahora he comprado el superior, wue tiene contador, y va perfectamente, facil de instalar y con instrucciones. Medicion exacta. Recomiendo el producto. El tamaño viene a ser tres magnetotermicos DPN.Es muy facil de instalar no necesita ser electricista pero si debe mantener unas medidas de seguridad, desconecte la electricidad del ICP o del Termico general de entrada. Mida que no haya corriente y siga las instrucciones de montaje. Puede pasar por el orificio tanto la fase como el neutro, solo uno. Tiene que alimentar desde el termico de alumbrado 10A con cable de 1.5mm el medidor Ketoket, en el tornillo 1 fase, en el 2 neutro. Si la instalacion es antigua puede ponerlo en cuadro ICP. Si es mas moderna en su cuadro y si no cabe, en uno exterior encima del cuadro. Pude ponerlo delante o detras del diferencial pero siempre protegido por delante de un termico y su alimentacion al de 10A.espero wue le pueda servir a slguien mi explicacion. ### ⭐⭐⭐⭐⭐ Instalaciones *by on Reviewed in Mexico 13 June 2026* Utilidad ### ⭐⭐⭐⭐⭐ Valido apparecchio *by on Reviewed in Italy 3 August 2026* L'apparecchio appare di buona qualità ed offre prestazioni allineate alla descrizione. Di facile installazione ed impatto visivo, sempre ben leggibile. Estremamente utile per la gestione efficace della potenza elettrica installata e la prevenzione di distacchi improvvisi per supero del limite. Si spera che le sue buone caratteristiche si mantengano inalterate nel tempo. ## Frequently Bought Together - KETOTEK Single Phase Energy Meter Din Rail Electricity Usage Monitor AC 40-300V 100A Voltmeter Ammeter Watt Kwh Frequency Power Meter Built-in CT 110V - smseace Distribution Protection Box, ABS Plastic Transparent Cover Waterproof Distribution Box IP65, for Indoor Wall Circuit Breaker (5 Way) - Chtaixi AC Miniature Circuit Breaker, 32 Amp 120V/240V 2 Pole DIN Rail Mount Circuit Breaker, Thermal Magnetic Trip, Solar AC Disconnect Switch MCB C32 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/475503511-ketotek-energy-meter-ac40-300v-100a-digital-display-led-voltmeter](https://www.desertcart.com.cy/products/475503511-ketotek-energy-meter-ac40-300v-100a-digital-display-led-voltmeter) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-09-28*
