Frequently Asked Questions
What exactly is a WiFi-enabled smart circuit breaker?

It's a circuit breaker with built-in WiFi for remote control and real-time energy monitoring via smartphone apps or voice assistants.

How does this intelligent breaker differ from traditional models?

Unlike traditional breakers, smart versions enable automation, usage tracking, and remote reset while maintaining standard protection features.

What's the working principle behind smart breakers?

They use current sensors and wireless connectivity to monitor electricity flow, allowing remote operation and overload protection.

Can these devices really reduce my electricity costs?

Yes, by identifying energy-hungry devices and optimizing usage patterns, they help lower power consumption over time.

Is professional installation required for smart breakers?

Yes, due to high-voltage wiring, installation should always be performed by a licensed electrician for safety.

What technical skills are needed to set one up?

While wiring requires electrical expertise, the app configuration is designed for user-friendly DIY setup.

How safe are internet-connected circuit breakers?

Reputable models use strong encryption and security protocols, making them safe when properly installed and maintained.

What safety certifications should I look for?

Always verify UL 489, IEC 60898, or CE certification to ensure compliance with international safety standards.

Will my breaker still function without WiFi?

Yes, it operates as a normal circuit breaker manually, but smart features become unavailable offline.

What happens during internet outages?

Basic protection continues working, while remote access and automations pause until connectivity returns.

How does a smart breaker compare to a smart switch?

Breakers protect entire circuits with overload protection, while switches only control individual devices.

When would I choose one over the other?

Use smart breakers for whole-circuit management and switches for individual appliance/lights control.

What's the proper way to reboot a smart breaker?

Turn it off, wait 10 seconds, then flip back on - same process as resetting traditional breakers.

How do I restore factory settings?

Use the physical reset button (if present) or the manufacturer's app to return to default configurations.
