Description
Track the energy used by two circuits on the same single-phase supply with Shelly EM Gen4. Current-transformer inputs make it useful for comparing appliance consumption and spotting changes in usage without routing the measured load through the meter.
Why you’ll love it
- Two measurement channels in a compact module.
- Keeps at least 30 days of one-minute records locally.
- A separate dry-contact output can control a suitably rated contactor.
Technical specifications
- Model: S4EM-002CXCEU; supply: 110–240 V AC, 50/60 Hz; consumption: <1 W.
- CT measurement range: up to 120 A with the appropriate compatible transformer; supports Shelly 50 A, 80 A and 120 A CTs.
- Measures active/apparent power and energy, voltage, current and power factor.
- Dry-contact output: maximum 2 A at 240 V AC; this is separate from the CT measurement rating.
- Wi-Fi, Bluetooth and Zigbee; Matter compatible. Local web interface and MQTT.
- Dimensions: 37 × 42 × 16 mm; ambient temperature: −20 to +40 °C.
Have a qualified electrician install it and select the correct current transformers, protection and contactor. The two channels share a single phase; this is not a three-phase meter.
