Carrier Single Pole / 1 Pole 30 Amp Replacement Condenser Contactor HN51KC024 by Carrier

POWER MEASUREMENT & CONTROL: Shelly 3EM gives owners enhanced safety and everyday control over appliances or machinery, along with the ability to make smart decisions about electrical consumption. The 3EM is a Wi-Fi energy measurement device, monitoring up to three phases between 110 and 240v per line..
MONOPHASE SYSTEMS: Shelly 3EM can calculate 2-way consumption: produced and used energy for each of the three phases. The device can be configured to measure three separate points of a mono-phase electrical system and measure each of them separately..
CONTACTOR CONTROL: Shelly 3EM has an integrated 10A relay output for contactor control..
NO HUB REQUIRED: You can control Shelly 3EM directly, no hub required. It is compatible with any Wi-Fi router. Or if you prefer you can connect it to your home automation platform..
OVERCONSUMPTION PROTECTION: Shelly 3EM can automatically notify and/or switch off the circuit if consumption or energy reaches the preset limit..
