TOMZN 63A Wi-Fi Smart Breaker & Energy Meter for eWeLink (TOB8-63WIFI)
This is not just a smart switch—it's your entire circuit, upgraded. Stop wondering what's using power or worrying about voltage spikes. At Abhir-Online, we're bringing you the ultimate tool for smart home control and safety. The TOMZN 63A Wi-Fi Smart Breaker (TOB8-63WIFI) combines a heavy-duty 63A circuit breaker, a precise energy meter, and an advanced protection device, all in an ultra-slim 18mm DIN rail body.
Connect it to your eWeLink app and take full control of any high-power circuit. Turn your AC, water heater, or even an entire sub-panel on or off from anywhere in the world. But the real power is in the data: see real-time Voltage (V), Current (A), and Power (W), and track your total KWh consumption over time. You can even download your history to see exactly where your money is going.
This device is your home's personal bodyguard. From the app, you can set adjustable protection limits. Set a maximum current (e.g., 50A) to prevent overload, or set a safe voltage range (e.g., 200V-250V) to automatically shut down the circuit and protect your valuable appliances from dangerous under-voltage or over-voltage spikes.
💡 The Technology Explained (in Simple Terms):
This is a Wi-Fi Smart Circuit Breaker with Metering & Protection.
- Remote Control: Use the eWeLink app or your voice (with Alexa/Google) to turn the circuit on or off.
- Energy Meter: See exactly how much power your circuit is using (KWh, V, A, W) in real-time and view historical charts.
- Adjustable Protection: Set your own limits! If the voltage or current goes outside your safe range, the breaker trips automatically to protect your equipment.
- Smart Automation: Set timers, schedules, or loop timers to automate your appliances. Turn on the water heater at 6:30 AM or run the pool pump for 2 hours every afternoon.
- App Setup:
- Connects directly to your 2.4GHz Wi-Fi network using the eWeLink app.
- Once added, link your eWeLink account to Amazon Alexa or Google Assistant for voice control.
Key Highlights:
- 📱 Full eWeLink App Control: Remote on/off, timers, schedules, and power monitoring from one app.
- 📈 Real-Time Energy Meter: Monitors KWh, Voltage, Current, and Active Power.
- 🛡️ Adjustable Protection: Set Over-Current, Over-Voltage, and Under-Voltage limits to safeguard your appliances.
- 🗣️ Voice Control: Works with Amazon Alexa and Google Assistant for hands-free commands.
- 💾 Consumption History: Tracks daily and monthly KWh usage and allows you to download the data.
- 📏 Ultra-Slim 18mm Body: Takes up only a single module space on your 35mm DIN rail.
Product Features and Advantages:
The TOB8-63WIFI is a revolution in a small package. Its 18mm width means it can fit into even the most crowded electrical panels, replacing an old breaker without taking up extra space. The eWeLink app integration is seamless, offering not just simple on/off, but a full suite of monitoring and automation tools. The adjustable protection features are its key advantage, offering a level of custom safety that a standard breaker cannot. You decide the safe operating limits for your sensitive electronics.
Applicable Applications and Practical Usage Scenarios:
- Main Circuit Breaker: Use it as the main smart breaker for a small apartment, guest house, or office to monitor total consumption.
- High-Power Appliance Control: Perfect for automating and protecting high-load items like water heaters, air conditioners, pool pumps, or EV chargers.
- Voltage-Sensitive Equipment: Install it on the circuit for your server room, home theater, or expensive computers to protect them from harmful voltage fluctuations.
- Rental Property Management: Monitor and control the power in a rental unit remotely. Track consumption and ensure power is off when the unit is vacant.

Frequently Asked Questions (FAQs):
- Q1: Does this device require a neutral wire?
- A1: Yes. As a smart device, it requires a Live (L) and Neutral (N) connection to power its internal Wi-Fi chip and electronics.
- Q2: What app does this use? Tuya or eWeLink?
- A2: This model (
TOB8-63WIFI) is specifically for the eWeLink app. It will not work with the Tuya or Smart Life apps.
- Q3: Can I reset the KWh (energy consumption) data?
- A3: Yes, unlike simple monitors, the eWeLink app allows you to view and download historical data, which typically includes daily and monthly totals that reset.
- Q4: What is the main benefit of "Adjustable Protection"?
- A4: A standard breaker only trips at its fixed rating (e.g., 63A). This smart breaker lets you set lower limits via the app. For example, you can set the over-current protection to 30A for a smaller circuit, or set the voltage protection to cut power if it drops below 200V, saving your appliances.
- Q5: Is this a "Circuit Breaker" (MCB) or a "Relay"?
- A5: It functions as both. It is a smart relay that allows remote and automatic control, built into the form factor of a Miniature Circuit Breaker (MCB) for easy DIN rail installation. It also provides overload and short-circuit protection features.
