The Ledgebit 4P63A Smart Circuit Breaker lets you control and protect your electrical system with ease. It connects to your Wi-Fi, so you can manage power from your phone using the Smart Life or Tuya App—no extra hub needed.

This breaker is great for homes, small shops, or offices where you want smart control over heavy devices like air conditioners, water heaters, or EV chargers. You can switch it on or off remotely, check power usage in real-time, and even get alerts if there’s a problem like overvoltage or a short circuit.

You can also set timers or schedules to save energy. For example, turn off the water heater every night or cut power during work hours. If you have a smart home setup, you can link it with other devices for automation. It even works with Alexa and Google Assistant for voice control.

The breaker supports 63A and has a four-pole (4P) design, meaning it can cut power on four lines. It fits standard DIN rail panels and is easy to install in most distribution boxes. It works with 90–280V AC and performs well indoors, in temperatures between -20°C to 60°C, and humidity up to 90%.

Made from strong, flame-retardant ABS+PC material, it’s built to last and keep your setup safe.

If you’re upgrading your setup, this breaker works well with other smart products in our Smart Switches Collection or Smart Devices range.

To sum up, the Ledgebit 4P63A Smart Circuit Breaker gives you smart control, remote access, and better safety—all in a compact and easy-to-use device.
