1 Phase Power Module 4G 40A
Overview
The Beakn 1 Phase Power Module 4G (40A) is a panel-mounted device that combines Class 1 energy monitoring with a built-in heavy-duty contactor — and connects to the internet over an embedded Airtel 4G SIM, with no WiFi or router required.
It monitors voltage, current, power factor, active power, and energy (kWh) on a single-phase 230V AC supply, and automatically disconnects the entire supply when voltage goes dangerously high (>280V) or low (<200V) — all from within the distribution panel, with no external contactor needed.
It is functionally identical to the WiFi 1 Phase Power Module 40A in every way — monitoring, protection, ratings, app experience, and voice control — except that connectivity is via cellular (Airtel 4G) instead of WiFi. This makes it the right choice for farm pumps, borewells, shops, remote panels, or any site where WiFi is weak, absent, or unreliable.
Features
1. Built-in Heavy-Duty Contactor
The contactor is integrated inside the unit — no separate external contactor is required. It physically switches the connected load (up to 40A) and automatically disconnects the entire supply when voltage exceeds safe limits. This makes it a complete monitor + protection + switching device in a single panel box.
2. Automatic Voltage Protection
•Disconnects supply when voltage rises above 280V (over-voltage)
•Disconnects supply when voltage drops below 200V (under-voltage)
•Reconnects automatically once voltage returns to the safe range
•Protects all connected appliances and equipment without any manual intervention
3. Embedded Airtel 4G SIM — No WiFi Required
•A 4G SIM is physically built into the device
•Connects over the Airtel cellular network on power-up
•No WiFi network, router, or password needed at any point
•Works independently of any on-site internet infrastructure
•Remains online and sending data wherever Airtel 4G coverage exists
4. Class 1 Accuracy Energy Monitoring
Real-time measurement of:
•Voltage (V)
•Current (A)
•Power Factor (PF)
•Active Power (W/kW)
•Energy Consumption (kWh)
All data is visible live in the Beakn app.
5. App + WhatsApp Alerts
Instant alerts sent to your phone via both the Beakn app and WhatsApp when:
•Voltage goes above 280V
•Voltage drops below 200V
•Power factor drops below 0.8
6. Voice Control
Compatible with Google Assistant, Amazon Alexa, and Apple Siri — control or query the device by voice.
7. Surge Tolerance
Handles voltage surges up to 4kV, protecting both the device and the connected circuit.
8. Panel-Ready Mounting
Designed to mount inside the distribution panel on a DIN rail — clean, professional, and space-efficient.

Installation & Wiring
What type of electrician is needed?
A regular electrician can install this. No specialist is required. Free professional installation is available in 8 cities.
Where does it mount?
Inside the distribution panel / DB box, on a DIN rail.
Wiring (Single-Phase)
The module wires into the incoming supply of the distribution panel:
```
Incoming Supply
│
Live (L) ──────► [INPUT L] ──► [BUILT-IN CONTACTOR] ──► [OUTPUT L] ──► Load
Neutral (N) ────► [INPUT N] ──────────────────────────► [OUTPUT N] ──► Load
```
•Neutral wire is mandatory — the device cannot function without a neutral connection
•The built-in contactor sits in-line with the live supply
•On a voltage event (>280V or <200V), the contactor opens, cutting the entire downstream supply
•When voltage returns to safe range, contactor closes and supply is restored
Connectivity Setup (4G)
•No WiFi setup required
•The embedded Airtel 4G SIM activates automatically on power-up
•The device comes online wherever Airtel 4G coverage is available
•Add the device in the Beakn app — no WiFi pairing step needed
•Readings, alerts, and control are then available through the app immediately
Important Installation Notes
•Neutral connection is non-negotiable — do not install without neutral
•Rated for supplies up to 40A — do not use on higher-rated circuits
•Designed for 230V AC single-phase only — not suitable for three-phase supplies (use the 3 Phase Power Module 4G 63A for those)
•Device does not replace the DISCOM / utility energy meter — it is an additional device on the customer's side of the panel
FAQ
Q: How is the 1 Phase Power Module 4G different from the 1 Phase Power Module (WiFi)?
Only the connectivity is different. The 4G model uses an embedded Airtel 4G SIM and connects over the cellular network — no WiFi needed. The WiFi model uses your 2.4GHz WiFi network. Every other specification — the 40A rating, built-in heavy-duty contactor, Class 1 monitoring, auto-disconnect thresholds, alerts, surge rating, app, voice control, and warranty — is identical.
Q: Does the 4G model need a WiFi network, router, or internet connection at the site?
No. The Airtel 4G SIM is embedded in the device. It connects to the internet over the cellular network on its own. There is no WiFi password to enter and no router needed at the installation site.
Q: Will it work at my farm / borewell / remote site?
Yes, as long as there is Airtel 4G cellular coverage at the location. No on-site WiFi or internet infrastructure is required.
Q: Does it need a neutral wire?
Yes — a neutral wire is required. The device wires into the incoming supply with live and neutral. Installation without neutral is not possible.
Q: Does it cut the supply automatically during a voltage problem?
Yes. The built-in heavy-duty contactor automatically disconnects the entire supply when voltage exceeds 280V (over-voltage) or drops below 200V (under-voltage). No external contactor, no external relay, and no human action is needed.
Q: What's the maximum load it can handle?
Up to 40A on a single-phase 230V AC supply — handled directly by the built-in contactor. No external contactor is required.
Q: How is the Power Module different from a Beakn energy meter?
A Beakn energy meter is a sensing device — it measures, monitors, and alerts, but needs a separate external contactor or Beakn switches/plugs to actually disconnect the supply. The Power Module has a heavy-duty contactor built in, so it can cut the entire circuit automatically during a voltage event, with no extra hardware.
Q: Does it replace my electricity board / DISCOM meter?
No. It is an additional device installed on the customer's side of the distribution panel for monitoring, protection, and automatic cutoff. It works alongside the utility meter, not in place of it.
Q: Can I control it by voice?
Yes — it works with Google Assistant, Amazon Alexa, and Apple Siri.
Q: Will I get alerts on WhatsApp?
Yes. Alerts for over-voltage (>280V), under-voltage (<200V), and low power factor (<0.8) are sent via both the Beakn app and WhatsApp.
Q: What is the warranty period?
3 years.
Q: Is installation free?
Free professional installation is available in 8 cities. A regular electrician can install it everywhere else.
