Aeotec Z-Wave Heavy Duty Smart Switch (40A Relay)

Product detailed description

The Smart Relay That Easily Handles Up To 40 Amps

Forget the limitations of standard smart relay modules meant for household lighting. The Aeotec Heavy Duty Smart Switch is an ultimate heavy-duty appliance switch built on cutting-edge industrial technology, specifically designed to safely manage extremely high electrical loads in both residential and commercial environments. With this robust Z-Wave relay, you can switch continuous loads up to an impressive 40 Amps (which equals up to 9,600 Watts of resistive load on a single phase). This opens up entirely new massive possibilities for home automation that previously required complex and bulky mechanical contactors wired in distribution boards.

Why and Where Should You Use the Heavy Duty Switch?

Thanks to its extreme load capacity and isolated IP44 waterproof enclosure suitable for indoor and covered outdoor environments (like garage walls or utility rooms), this relay is the perfect tool for Smart Home integration of appliances with massive power draws:

• Electric Vehicle (EV) charging stations and high-power wallboxes.
• Powerful sauna heaters, electric fireplaces, and outdoor hot tubs (jacuzzis).
• Industrial heating mats, massive electric pool heaters, or home heat pumps.
• Large induction cooktops and huge air conditioning or compressor (PAC) units.

Precise Energy Monitoring and Massive Cost Savings

High-power electronics featuring heating elements are undoubtedly the most expensive items on your annual electricity bill. The Heavy Duty Switch contains an incredibly accurate metering chip that continuously reports current and cumulative energy consumption (in Watts and kWh) in real-time to your smart home hub (e.g., FIBARO, Homey, SmartThings), maintaining a maximum deviation of just ±1% under high loads.

No heavy-duty appliance needs to be powered on 24/7. Using your Z-Wave controller, you can precisely schedule a massive water boiler to heat exclusively during off-peak (cheap night) electricity hours. Furthermore, you can set up intelligent automations to instantly cut power to connected appliances remotely in an emergency (such as when a smart water leak or smoke detector is triggered), protecting your home from devastating fires and water damage.
