Product Description

This 63A Smart Circuit Breaker is a high-capacity, professionally-oriented device designed to bring intelligent control and enhanced safety to heavy-duty electrical systems. It functions as a remotely operated switch for major appliances, HVAC units, or sub-panels, enabling automated or voice-activated power management through integration with Google Home, Amazon Alexa, and other smart platforms via Wi-Fi.

Constructed with a dedicated grounding wire, it ensures strict compliance with essential electrical safety standards, including UL certification for reliable operation. A key safety feature is its double-break mechanism, which simultaneously disconnects both the live and neutral wires, providing superior protection during overloads or when switched off. The robust design is housed in a flame-retardant casing for maximum durability.

Ideal for smart upgrades to water heaters and commercial equipment, or as the main circuit breaker for sheds/workshops, offering convenient operation and robust circuit protection.
