Precision Energy Monitoring
The Shelly 50A clamp enables you to monitor the exact energy consumption of individual circuits or appliances in your home or business. With 1% accuracy and a 20-ohm load resistance, you'll get reliable data for tracking power usage patterns, identifying energy-hungry devices, and reducing electricity costs. The clamp features a 10mm internal diameter that fits around most standard installation wires.
Robust Construction & Electromagnetic Shielding
Built with a ferrite core, this current transformer clamp effectively blocks low-frequency noise and suppresses electromagnetic emissions for clean, accurate readings. Rated for 3000 VAC electrical strength, it's designed for safe, long-term operation in demanding electrical environments. The saturation current rating of ≥85A provides headroom for temporary current spikes.
Smart Home Integration
When paired with a Shelly EM energy meter, this clamp integrates seamlessly with the Shelly Cloud app, allowing you to monitor energy consumption on your smartphone or tablet. Track usage by day, week, month, or year, and integrate with Home Assistant, Amazon Alexa, Google Assistant, and other smart home platforms via MQTT, CoAP, and REST API.
Compatibility
Compatible with: Shelly EM, Shelly 3EM
NOT compatible with: Shelly Pro EM-50, Shelly Pro 3EM, Shelly EM Gen3, Shelly EM Gen4, Shelly Pro 3EM-3CT63
Please verify your energy meter model before ordering. For newer Gen3, Gen4, and Pro models, a different clamp is required.
