Elk Heavy Duty Relay with Box
We appreciate this relay because it’s easy to install — everything you need is in the box and there’s no scavenging for extra adapters or enclosures. Pairing it with a smart plug or automation module (Z-Wave, Zigbee, or similar) gives you remote on/off control of heavy devices like well pumps, heaters, or motors. Over years of use it’s been very reliable and rock solid, with the enclosure offering peace of mind and the plug-in cord simplifying integration.
Elk Heavy Duty Relay
The ELK Heavy-Duty Relay is a solid, no-nonsense relay solution for automating high-current devices in your smart home setup. Designed to handle up to 30 Amps of AC load, this relay comes housed in a sturdy lockable metal enclosure — and importantly for automation applications, it includes the power cord and integrated switch that lets you plug into a smart plug or appliance module without extra wiring hassles.
