Smart 63A Unit Lock Breaker – Power Control with Monitoring & Expense Control

Smart 63A Unit Lock Breaker – WiFi Circuit Breaker with Live Monitoring, Unit Limit Control & App Locking

Take command of your electricity like never before. The Smart 63A Unit Lock Breaker is a next-generation WiFi smart circuit breaker that replaces your old MCB with an intelligent power management device — one that tracks consumption, enforces unit limits, locks on command, and protects your home around the clock.

Whether you’re managing a home, a rental property, a shop, or a small office, this smart breaker fits directly into your electrical panel and pairs with your phone within minutes. No more guesswork. No more surprise bills. Just complete, real-time control.

📊 Monthly Unit Control

One of the most practical features for Pakistani households is the monthly unit limit setting. You can define a maximum electricity consumption threshold directly from the app. Once the circuit reaches that limit, the breaker automatically cuts off — helping you stay within WAPDA or LESCO unit slabs, avoid expensive billing tiers, and prevent overuse by tenants or family members. This is especially valuable for anyone trying to stay under a 200-unit or 500-unit monthly threshold.

⚡ Live Electricity Monitoring

See exactly what’s happening on your circuit at any moment. The Smart 63A Unit Lock Breaker displays real-time voltage, current (amperage), active wattage, and cumulative kWh consumption — all updated live in the app. No more wondering which appliance is spiking your bill. Whether it’s your AC, water motor, electric geyser, or a full room line, you’ll know the exact power draw at all times.

This pairs well with our Smart Circuit Breakers collection for those building a comprehensive energy monitoring setup across multiple circuits.

🔴 Auto OFF on Limit

Set your safe operating threshold and let the breaker do the rest. The Auto OFF on Limit feature automatically trips the breaker when consumption, current, or voltage crosses your defined safe range — protecting your appliances from damage before any physical harm occurs. This is far smarter than a standard MCB, which only trips under a physical fault. Think of it as a programmable safety net working silently in the background.

⏱️ Timer & Scheduling

Stop wasting electricity on circuits that nobody is using. With the built-in timer and scheduling feature, you can programme the breaker to turn on or off at specific times every day — or on selected days of the week. Schedule your geyser to heat water only before morning peak hours. Cut power to a room or shop after business hours automatically. Set your AC circuit to switch off at midnight. The scheduling runs even when your phone is offline, as it syncs with the cloud.

🔒 App-Based Locking (Remote Lock/Unlock)

This is the feature that sets the Smart 63A Unit Lock Breaker apart from any standard smart plug or relay. The app-based locking system lets you lock the breaker from your phone so that it cannot be manually reset at the panel — not by a tenant, not by a worker, not by anyone without your phone access. With one tap you can fully disable a circuit remotely, even if you’re hundreds of kilometres away.

This makes it invaluable for:

• Rental property owners controlling a tenant’s electricity
• Shop owners cutting power after closing time
• Parents restricting electricity in a teenager’s room
• Factory managers controlling employee area circuits

Works over both WiFi and cloud, so remote access is reliable regardless of network.

🛡️ Full Home Protection

The Smart 63A Unit Lock Breaker delivers multi-layer protection:

• Overvoltage & Undervoltage Alerts — Receive instant phone notifications if voltage drops dangerously low or spikes above safe levels
• Overcurrent Protection — Alerts and auto-trip when amperage exceeds the safe load range
• Overload Detection — Monitors watt usage and flags abnormal load spikes before they cause short circuits or appliance damage
• Overheating Safeguards — Built with heat-resistant casing and high-quality internal components designed for continuous use under Pakistan’s unstable grid conditions

This isn’t just a breaker — it’s a 24/7 digital guard for your electrical panel.

📋 Technical Specifications

🔧 Easy Installation

Installation follows the same process as a standard MCB, so any licensed electrician in Pakistan can mount and wire it in under 30 minutes. Once installed, pairing with the Tuya Smart or Smart Life app takes just a few minutes via WiFi. The interface is clean, in plain language, and requires no technical background to operate daily.

💡 Who Is This For?

• Homeowners tired of shock electricity bills wanting real visibility into usage
• Landlords & property owners managing tenant electricity with remote lock control
• Shop owners automating power cutoff after business hours
• Parents restricting electricity access in specific rooms
• Small businesses & offices needing circuit-level monitoring and scheduling

🏗️ Built for Pakistan

Unlike generic smart plugs rated for light loads, this breaker is purpose-engineered for 63A heavy circuits — air conditioners, water motors, geysers, and full room power lines. Its components are rated for continuous heavy-duty use and are built to withstand the voltage fluctuations typical of the Pakistani power grid.
