3 Phase Power Module (63A)
Overview
The Beakn 3 Phase Power Module (63A) is a panel-mounted device designed for three-phase electrical installations. It combines Class 1 accuracy energy monitoring with a built-in heavy-duty contactor in a single unit — so it both measures your electrical supply in real time and can automatically cut it off when something goes wrong, all without any additional external hardware.
It monitors all three phases (R, Y, B) individually — tracking voltage, current, power factor, active power, and total energy consumption — and connects directly to the Beakn cloud over 2.4GHz WiFi (no hub required). When voltage goes dangerously high or low, the built-in contactor disconnects the entire supply automatically and sends you an instant alert via the Beakn app and WhatsApp.
It is the go-to choice for three-phase homes, villas, or premises where you want whole-supply protection, per-phase visibility, and remote monitoring — all in one panel-box device.
Features
•Built-in heavy-duty contactor — handles up to 63A directly; no external contactor needed for whole-circuit cutoff
•Per-phase monitoring — individual voltage, current, and power factor readings for each of the three phases (R, Y, B)
•Class 1 accuracy metering — commercial-grade precision for voltage, current, power factor, active power, and energy (kWh)
•Automatic voltage protection — contactor trips and cuts the entire supply if voltage rises above 280V or falls below 200V
•Instant alerts — Beakn app notifications and WhatsApp messages on voltage events and low power factor (<0.8)
•4kV surge capability — built-in protection against transient voltage spikes
•WiFi 2.4GHz, no hub — connects directly to the cloud straight out of the box
•Voice control — compatible with Google Assistant, Amazon Alexa, and Apple Siri
•Panel-box / DIN rail mounting — fits neatly inside the existing distribution panel
•3-year warranty
•Free professional installation in 8 cities
Use Cases
•Three-phase homes and villas — whole-supply monitoring and protection for large residential properties with three-phase connections
•High-load premises — anywhere drawing up to 63A across three phases (large ACs, pumps, lifts, heavy appliances)
•Voltage fluctuation protection — locations prone to over-voltage or under-voltage events; the contactor disconnects automatically before damage occurs
•Power quality monitoring — track per-phase power factor and get alerted when it drops below 0.8, helping identify inefficient loads
•Remote energy management — monitor real-time consumption per phase from anywhere via the Beakn app; integrate with voice assistants for hands-free control
•Landlords and property managers — single-device solution for monitoring and protecting a three-phase panel without rewiring or adding external contactors
•Replacing a standalone energy meter + external contactor setup — consolidates two devices into one panel-box unit

Selling Points
1.All-in-one panel device — monitoring + protection + switching in a single DIN-rail unit; no external contactor, no separate relay panel
2.True automatic protection — the contactor trips the entire three-phase supply itself on a voltage event; no manual intervention required
3.Per-phase visibility — see what's happening on R, Y, and B independently, not just a combined total
4.Class 1 metering accuracy — the same accuracy class used in commercial energy meters
5.Instant multi-channel alerts — app notification AND WhatsApp message the moment something goes wrong
6.4kV surge tolerance — protects connected equipment from transient spikes
7.No hub needed — works straight out of the panel over existing 2.4GHz WiFi
8.Voice assistant integration — Google, Alexa, and Siri support out of the box
9.Installed by any electrician — plus free installation in 8 cities lowers the barrier to adoption
10.3-year warranty — long-term peace of mind for a safety-critical device

Installation & Wiring
Who installs it?
A regular licensed electrician. No specialist is required. Beakn also offers free professional installation in 8 cities.
Where does it mount?
Inside the distribution panel (panel box) on a DIN rail.
Wiring connections
The module wires into the incoming supply of the distribution panel:
| Wire | Connection |
|---|---|
| R (Phase 1) | Incoming live — Phase R |
| Y (Phase 2) | Incoming live — Phase Y |
| B (Phase 3) | Incoming live — Phase B |
| Neutral | Required — must be connected |
> ⚠️ Neutral is mandatory. The device cannot operate without a neutral connection.
How the contactor works
The built-in heavy-duty contactor sits in-line with the supply. Under normal conditions it remains closed (supply flows through). If voltage on any phase crosses the safe limits (>280V or <200V), the contactor opens automatically, cutting the entire three-phase supply to the panel. No external contactor, no Beakn switches, no additional Safe Mode devices are needed.
Pairing
After physical installation, pair the device to your home's 2.4GHz WiFi network using the Beakn app. The device connects directly to the Beakn cloud — no hub or gateway is required.
Load limit
The built-in contactor is rated for up to 63A. Do not install on a supply exceeding this rating.
FAQ
Q: How is this different from a Beakn Energy Monitoring meter?
A Beakn energy meter measures and alerts — but to cut the supply, it needs either an external contactor or Beakn switches/plugs operating in Safe Mode. The 3 Phase Power Module has the heavy-duty contactor built in. It senses the problem and disconnects the supply itself, automatically, in one box. No extra hardware required.
Q: Does the neutral wire need to be connected?
Yes, absolutely. The device wires into the incoming supply with neutral. All four conductors — R, Y, B, and Neutral — must be connected. It will not work without the neutral.
Q: What exactly triggers the auto-disconnect?
The built-in contactor will automatically open (cutting the supply) if voltage rises above 280V or falls below 200V on any phase. You will receive an alert on the Beakn app and via WhatsApp at the same time.
Q: What alerts will I receive?
•Voltage above 280V
•Voltage below 200V
•Power factor below 0.8 (on any phase)
Alerts are delivered via the Beakn app and WhatsApp.
Q: Does this replace my DISCOM / utility meter?
No. It is a separate device installed on your side of the panel. Your DISCOM meter remains in place; the Power Module sits downstream for monitoring, protection, and automatic cutoff.
Q: Can I control it remotely or via voice?
Yes. You can monitor and control it remotely through the Beakn app. It is also compatible with Google Assistant, Amazon Alexa, and Apple Siri.
Q: Do I need a hub or smart home gateway?
No. The module connects directly to the cloud over your home's 2.4GHz WiFi. No hub, no bridge, no extra hardware.
Q: Can a regular electrician install it?
Yes. No specialist is needed. Beakn also provides free professional installation in 8 cities.
Q: What is the surge protection rating?
The device can withstand transient surges of up to 4kV.
Q: Is this suitable for commercial premises?
The device is engineered for any three-phase installation up to 63A — large homes, villas, and small commercial premises with a three-phase supply are all valid use cases.
Q: What does per-phase monitoring mean?
Instead of a single combined reading, you get individual voltage, current, and power factor data for each of the three phases (R, Y, B). This makes it much easier to identify imbalanced loads or single-phase problems within a three-phase setup.
Q: What is the warranty period?
3 years.
