Energy Meter 1 Phase 20a Din Rail — product pageDesigned page · specs & gallery
Overview
The Beakn Energy Meter 1 Phase 20A DIN-Rail is a single-phase home energy monitor designed for installation inside a residential distribution panel. It mounts on a standard 35mm DIN rail — right alongside your existing MCBs — and measures current through one external split-core CT clamp (included) that simply wraps around the live wire. No cutting, no splicing, no rewiring.
Once installed, it reads voltage, current, power factor, active power, and energy (kWh) every second, pushing live data to the Beakn app and sending instant WhatsApp alerts when your home's electricity strays outside safe limits. Paired with Beakn smart switches or plugs in Safe Mode, it can automatically disconnect enrolled appliances during a voltage event — protecting your refrigerator, AC, washing machine, and other sensitive equipment without you lifting a finger.
It is the right choice for 1BHK and 2BHK single-phase homes that have a DIN-rail distribution panel and a total load up to 20A.
Features
Real-Time Energy Monitoring
•Reads voltage, current, power factor, active power, and kWh every second
•Live wattage visible in the Beakn app at all times
•Today's kWh, this month's total, and estimated cost based on your DISCOM tariff
•Daily and monthly budget alerts
•6 months of cloud history to pinpoint when consumption spiked
High/Low Voltage Protection
•Monitors voltage continuously; triggers an instant app and WhatsApp alert when voltage exceeds 280V or drops below 200V
•Alert includes the exact voltage reading at the time of the event
•Sustained voltage outside the safe band damages AC compressors, fridge motors, and TV power supplies — early warning prevents expensive repairs
Safe Mode Auto-Disconnect
•When a voltage event is detected, the Beakn cloud sends an OFF command to every enrolled Beakn smart switch or plug within seconds
•The monitor itself is a sensor/alert device — it has no built-in contactor and does not switch heavy loads directly
•Non-Beakn appliances receive the alert only; connect them through a Beakn Smart Plug to bring them into Safe Mode
•For whole-circuit cutoff, the built-in low-current relay can drive an external contactor (sold separately)
Power Factor Monitoring
•Alerts when power factor drops below 0.8 — a reliable early-failure indicator for AC compressors and motors
•An early AC service call (≈₹1,500–2,500) catches problems 3–6 months before a burned-out compressor (₹8,000–15,000+)
WhatsApp + App Alerts — No Subscription
•Critical alerts (voltage spike, voltage drop, power factor drop, device offline) delivered via WhatsApp and the Beakn app
•No subscription fee, ever
WiFi — No Hub
•Connects directly to 2.4GHz WiFi and the Beakn cloud
•No additional hub or bridge required
Offline Resilience
•Continues reading locally if WiFi drops
•Queues alerts and delivers them on reconnect
•Safe Mode disconnect resumes automatically when connectivity returns
Voice Control
•Works with Google Assistant, Amazon Alexa, and Apple Siri for hands-free status queries

Installation & Wiring
What's in the Box
•1× Beakn Energy Meter (DIN-rail body)
•1× Split-core CT clamp (for the live wire)
Who Should Install
A regular electrician. The install is straightforward and typically takes 15–30 minutes inside the distribution panel. Free professional installation is available in 8 cities — check the Beakn app or website for your city.
Step-by-Step Overview
1.Mount on DIN rail — Clip the meter body onto the 35mm DIN rail inside your panel, next to the existing MCBs.
2.Connect live and neutral — Connect the incoming live wire and neutral wire to the meter's power terminals. The neutral connection is mandatory.
3.Clamp the CT — Open the split-core CT clamp and snap it around the live wire only (not neutral). No cutting or splicing of any wire. Close the clamp and connect its lead to the CT input on the meter.
4.Close the panel — The panel cover closes back normally over the installed meter.
5.Pair to WiFi — Open the Beakn app, add the device, and connect it to your 2.4GHz WiFi network (5GHz is not supported).
6.Enter your DISCOM tariff — Input your electricity rate in the app to enable cost estimates and budget alerts.
Wiring Summary
| Terminal | Connection |
|---|---|
| Live (L) | Incoming single-phase live wire |
| Neutral (N) | Neutral wire (required) |
| CT input | CT clamp lead from the live wire |
| Relay output | Optional — connect to external contactor (sold separately) for whole-circuit cutoff |
Important Notes
•2.4GHz WiFi only — the meter will not connect to a 5GHz band. If your router broadcasts both, ensure the 2.4GHz SSID is available during setup.
•Neutral is mandatory — the meter cannot function without a neutral connection.
•CT on live wire only — clamping around both live and neutral cancels the magnetic field and gives a zero reading.
•The meter does not replace your DISCOM billing meter; it runs in parallel as a sub-meter on your side of the panel.
•For automated whole-circuit cutoff during a voltage event, an external contactor must be wired to the built-in relay (contactor sold separately). Most users protect individual appliances via Beakn smart switches/plugs in Safe Mode instead.
FAQ
Q: Does this replace my DISCOM smart meter?
No. Your DISCOM meter is the sealed legal billing meter. The Beakn DIN-Rail meter is a separate sub-meter on your side of the panel — both run in parallel. The Beakn meter gives you real-time monitoring and protection; it has no effect on your official billing meter.
Q: Why DIN-rail instead of a Box meter for my home?
If your distribution panel has a standard 35mm DIN rail (the most common panel type in India), the DIN-rail meter is the natural fit — it mounts alongside your MCBs and measures via a non-invasive CT clamp. It also supports up to 20A versus 16A for the 1-Phase Box. If you want the simplest possible inline install on a lighter load (up to 16A), the 1-Phase Box 16A is the alternative.
Q: Is the CT clamp included?
Yes. One split-core CT clamp is included in the box. The 3-year warranty also covers the CT clamp.
Q: Do I need to cut or splice any wires for the CT clamp?
No. The split-core CT clamp snaps open, wraps around the live wire, and closes again. No cutting, no splicing, no interruption to your power supply during installation.
Q: Will the meter automatically cut power if voltage spikes?
The meter detects the event and sends alerts instantly via app and WhatsApp. For automatic disconnect: enrolled Beakn smart switches and plugs in Safe Mode receive an OFF command from the cloud within seconds. The meter itself has no built-in contactor for heavy loads. For whole-circuit cutoff, wire an external contactor (sold separately) to the meter's built-in low-current relay.
Q: My appliance isn't a Beakn device — will it disconnect automatically?
Non-Beakn appliances receive the alert only (app + WhatsApp). To automate their disconnect, plug them into a Beakn Smart Plug and enroll it in Safe Mode.
Q: What if my WiFi goes down?
The meter keeps reading locally and queues any alerts, delivering them once WiFi is restored. Safe Mode disconnects require WiFi (cloud sends the OFF command), so Safe Mode protection resumes automatically when connectivity returns.
Q: Does it need a subscription?
No. All alerts (voltage, power factor, device offline), the 6-month cloud history, app features, and voice assistant integrations are included with no subscription fee.
Q: Does it work on 5GHz WiFi?
No — WiFi 2.4GHz (802.11 b/g/n) only. Ensure your router's 2.4GHz band is active and its SSID is visible during pairing.
Q: What homes is this right for?
Single-phase homes — typically 1BHK or 2BHK — with a DIN-rail distribution panel and a total load up to 20A. If your home is three-phase or your load exceeds 20A, you need a different model.
Q: My home has three-phase supply — will this work?
No. This meter is single-phase only (live + neutral). For a three-phase home, choose the Beakn 3-Phase Energy Meter 100A DIN-Rail (three CTs included) or the 3-Phase Box 60A.
Q: Can it monitor individual circuits or appliances?
This meter monitors the whole-home single-phase incoming supply. For per-appliance monitoring and control, pair it with Beakn Smart Plugs or Switches.
Q: What is power factor and why does the alert matter?
Power factor is a measure of how efficiently an appliance (typically a motor — AC compressor, refrigerator, washing machine) uses electricity. A reading below 0.8 often signals coil wear or refrigerant issues, typically 3–6 months before outright failure. The alert lets you schedule a service call before the compressor burns out.
Q: Is professional installation available?
Yes — free professional installation is available in 8 cities through the Beakn app or website.
