High-Current Applications (Maximum Current 100A): External current transformers (CTs) must be used. The electrical meter measures high current indirectly via CTs. Typical Applications:Residential energy monitoringSmall business power trackingElectrical sub-meteringLoad management systems Compliance Information: This DIN-rail Kilowatt Hour kwh Meter is designed for AC circuits only.It is recommended that the kilowatt meter be installed in the electric meter box.Professional installation recommendedFor optimal performance and safety, we recommend installation by a qualified electrician professional installation. ## Features - Accurate Single-Phase Energy Meter – Class 1.0 accuracy kWh meter designed for precise power consumption measurement in 110V/220V split-phase systems (L1-L2 = 220V, L1-N/L2-N = 110V). Ideal for residential and light commercial sub-metering. - Wide Compatibility & High Capacity – Supports 10(100)A current range (max 100A) and operates at 60Hz ±10%. Features a starting current of 40mA for sensitive load detection. (Note: For continuous high-current applications, external CTs are required but NOT included). - Clear LCD Display & Pulse Output (Non-WiFi) – Adopted advanced micro-electronic techniques with a clear LCD display featuring a 6+1-digit readout (up to 999,999.9 kWh). Includes a passive pulse output (800imp/kWh) for easy tracking. Please note: This is a basic electronic meter without WiFi or smart app connectivity. - Durable & Easy Installation – Standard 35mm DIN rail-mounted design with an environmentally friendly, flame-retardant PC housing. Rated for harsh -25°C to 70°C environments and meets an AC withstand voltage of 4000V/25mA for reliable safety. - For Three-Wire Systems Only – Specifically compatible with single-phase three-wire (L1, L2, N) configurations. The neutral line bypasses the meter (Not suitable for two-wire L-N systems). For optimal performance and safety, professional installation by a qualified electrician is highly recommended. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B078V3KD46 | | Best Sellers Rank | #52,281 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #13 in Industrial Power Meters #82 in Voltage Testers | | Brand Name | Baomain | | Customer Reviews | 4.3 4.3 out of 5 stars (83) | | Included Components | Single-Phase Three-Wire Energy Meter | | Item Highlight | DDS238-4-R Submeter: 10A(100A), 60Hz, Basic LCD Display (Non-WiFi).

L1,L2 works through meter which is 220v, N have not work through meter. L1-N =110V, L2-N=110V, L1-L2=220V This meter will not work on a single phase 120v 2-wire system. **Q: Have an apt fed by 100amp double breaker in house panel. can i mount this next panel with pigtails to meter? apt feed is 240v. two hots and a neutral** A: Yes. All you need are two hots and two small jumper wires as per the instructions. Then hook up whatever you wish to monitor as per the instructions. Its simple and easy. No neutral wire needed. ## Frequently Bought Together - Baomain DDS238-4-R DIN-Rail Single Phase Three Wire Energy Meter 110V 220V 60Hz 10 (100) A - LMioEtool ABS Plastic Dustproof Waterproof IP65 Junction Box Hinged Shell Universal Electrical Project Enclosure Gray, with PC Transparent Clear Cover 8.7 x 6.7 x 4.3inch(220 x170 x110mm) - 1 Piece DIN Rail Slotted Aluminum RoHS 12" Inches Long 35mm Wide 7.5mm High --- ## 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.vn/products/54374208-baomain-single-phase-3-wire-din-rail-kwh-meter-110v](https://www.desertcart.vn/products/54374208-baomain-single-phase-3-wire-din-rail-kwh-meter-110v) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-09-17*
