1 Phase Power Module (40A)
Overview
The Beakn 1 Phase Power Module (40A) is a single-phase panel-box device that combines Class 1 accuracy energy monitoring with a built-in heavy-duty contactor in a single unit. It installs inside your distribution panel (DIN rail), wires into the incoming single-phase supply (230V AC, live + neutral), and simultaneously measures your electrical parameters in real time and acts on them — automatically cutting the supply when voltage goes out of safe limits, without needing any external contactor or additional hardware.
This is the key distinction from Beakn's energy monitoring meters: the Power Module does not just sense and alert — it also switches the load itself, protecting the whole circuit in one box.
Features
Built-in Heavy-Duty Contactor
•The contactor is integrated directly into the module — no external switching hardware needed.
•Handles up to 40A through the contactor directly.
•Automatically disconnects the supply when a voltage event is detected (>280V or <200V).
•Can also be manually controlled via the Beakn app or voice commands.
Class 1 Accuracy Energy Monitoring
•Real-time measurement of:
•Voltage (V)
•Current (A)
•Power factor (PF)
•Active power (W/kW)
•Energy consumption (kWh)
•Class 1 accuracy — reliable, precise metering data.
Automatic Over/Under Voltage Protection
•The built-in contactor automatically cuts the supply when:
•Voltage rises above 280V (overvoltage)
•Voltage drops below 200V (undervoltage)
•No external contactor, no additional relay, no extra wiring required.
Smart Alerts
•Instant notifications via the Beakn app and WhatsApp when:
•Voltage exceeds 280V or drops below 200V
•Power factor falls below 0.8
•Alerts are delivered even when you are away from home.
Surge Protection
•Built-in surge capability up to 4kV, adding a layer of protection against transient voltage spikes.
WiFi Connectivity — No Hub
•Connects directly to your home WiFi on 2.4GHz.
•Communicates directly to the cloud — no Beakn hub or gateway required.
•Set up and paired through the Beakn app.
Voice Control
•Compatible with Google Assistant, Amazon Alexa, and Apple Siri for hands-free operation.
Panel-Mounted, Electrician-Installed
•Designed for installation inside the distribution panel on a DIN rail.
•Installed by a regular (non-specialist) electrician.
•Free professional installation available in 8 cities.
Use Cases
| Scenario | How the 1 Phase Power Module helps |
|---|---|
| Whole-home single-phase supply protection | Monitors incoming 230V supply and auto-disconnects if voltage goes dangerously high or low — protecting all appliances on the circuit simultaneously. |
| High-value appliance protection | Prevents damage to ACs, refrigerators, washing machines, and other sensitive equipment from over/undervoltage events. |
| Energy consumption tracking | Accurate kWh monitoring at the panel level — track whole-home energy usage in the Beakn app. |
| Power quality monitoring | Alerts on poor power factor (<0.8) and voltage anomalies — helps identify grid-side or installation-side issues. |
| Rental properties / remote monitoring | Owners get app + WhatsApp alerts instantly, even when not on site. |
| Homes without smart switches or plugs | Unlike Safe Mode on energy meters (which needs Beakn switches/plugs to cut load), this module provides whole-circuit cutoff on its own. |
| Replacing an external contactor setup | Consolidates monitoring + contactor into one panel-box unit, reducing wiring complexity and panel space. |

Selling Points
1.All-in-one protection + monitoring — combines a Class 1 energy meter and a heavy-duty contactor in a single panel-box unit. No second device, no extra wiring.
2.Automatic whole-circuit cutoff — disconnects the entire single-phase supply the moment voltage goes dangerously high (>280V) or low (<200V), protecting every appliance on the circuit simultaneously.
3.No external contactor needed — unlike energy meters that depend on Safe Mode or a separately wired contactor, this module acts on its own.
4.Dual alerts — app + WhatsApp — instant notifications wherever you are, on the channels people actually check.
5.Class 1 accuracy metering — utility-grade monitoring of voltage, current, power factor, active power, and kWh.
6.4kV surge protection — guards against transient spikes on top of over/undervoltage cutoff.
7.No hub, no complexity — direct 2.4GHz WiFi to cloud. Simple setup, fewer points of failure.
8.Voice control on all three major platforms — Google, Alexa, and Siri.
9.Easy, affordable installation — fits any standard distribution panel on a DIN rail; any regular electrician can install it; free installation in 8 cities.
10.3-year warranty — strong backing for a panel-level protection device.

Installation & Wiring
Who Installs It
•A regular licensed electrician — no specialist certification required.
•Free professional installation is offered in 8 cities (check Beakn website for city list).
Where It Mounts
•Inside the distribution panel (DB box) on a DIN rail.
Wiring Requirements
•Single-phase incoming supply: Live + Neutral — both are required.
•A neutral wire connection is mandatory — the module cannot operate without neutral.
•The built-in contactor is wired in-line with the load — it directly switches the circuit up to 40A.
Wiring Summary
```
Incoming Supply (230V AC)
|
[Live wire] ──────→ [Power Module — Live IN]
[Neutral wire] ───→ [Power Module — Neutral IN]
|
[Power Module — Live OUT] ──→ Load / Distribution
[Power Module — Neutral OUT] → Load / Distribution
```
The module wires into the incoming supply side of the panel, before the load distribution, so it can cut the whole supply if needed.
Pairing to WiFi
•Pair the device to 2.4GHz WiFi through the Beakn app after physical installation.
•No hub or additional gateway required.
Important Notes
•Does not replace the DISCOM utility meter — it is a separate protection and monitoring device installed on the customer's side of the panel.
•Ensure load does not exceed 40A through the module.
•Surge withstand: up to 4kV — provides additional transient protection.
FAQ
Q: How is the 1 Phase Power Module different from a Beakn energy monitoring meter?
A: A Beakn energy meter only measures and sends alerts — to cut the circuit, it needs Beakn smart switches/plugs operating in Safe Mode or a separate external contactor. The 1 Phase Power Module has a heavy-duty contactor built in, so it can automatically disconnect the whole single-phase supply by itself during a voltage event. No extra hardware needed.
Q: Does it need a neutral wire?
A: Yes. The module wires into the incoming single-phase supply (live + neutral) and neutral is mandatory for correct operation.
Q: What current can it switch?
A: Up to 40A directly through its built-in contactor. No external contactor is required or needed.
Q: What voltage events trigger an automatic disconnection?
A: The built-in contactor automatically cuts the supply when voltage rises above 280V (overvoltage) or drops below 200V (undervoltage).
Q: Will I get a notification when it disconnects?
A: Yes — you receive an alert via the Beakn app and WhatsApp on voltage >280V, voltage <200V, or power factor <0.8.
Q: Does it replace my electricity company (DISCOM) meter?
A: No. It is a separate device installed on your side of the panel for monitoring, protection, and automatic cutoff. It works alongside the utility meter.
Q: Does it need a hub or gateway?
A: No. It connects directly to 2.4GHz WiFi and communicates directly to the Beakn cloud. No hub required.
Q: Can I control it with my voice?
A: Yes — it works with Google Assistant, Amazon Alexa, and Apple Siri.
Q: Can a regular electrician install it?
A: Yes. No specialist certification is needed. Beakn also offers free professional installation in 8 cities.
Q: What is the warranty?
A: 3 years.
Q: Does it protect against power surges?
A: Yes — it has a surge withstand capability of up to 4kV.
Q: I have a three-phase supply — is this the right product?
A: No. For three-phase supplies, use the Beakn 3 Phase Power Module (63A), which handles 415V AC, up to 63A, with per-phase monitoring and a built-in contactor.
Q: Can I monitor energy consumption from the app?
A: Yes — the module provides real-time and historical data on voltage, current, power factor, active power, and kWh consumption through the Beakn app.
