Shelly 80A Current Transformer - Precision Ammeter Clamp with Dedicated Connector (for EM Gen3)

TheShelly 80A CT Clamp is a high-precision measuring accessory specifically designed to work with next-generation energy monitoring devices such as the Shelly EM Gen3. This ammeter clamp allows AC current monitoring without the need to break the circuit or cut wires, providing a safe, non-invasive and highly accurate method of monitoring power consumption or production.

Key Selling Points

• Non-Invasive Measurement: The split-core design allows the clamp to be installed by simply clamping around the phase conductor. There is no need to disconnect the wires from the electrical panel, greatly reducing installation time and installation risks.

• Plug & Play Connector for Gen3: This version comes equipped with a specialised connector designed for a perfect fit and stable connection with the input ports of Shelly EM Gen3 devices. No more loose wires that require tightening in the terminals.

• Class 1 Accuracy: When used with compatible Shelly monitors, the clamp provides high (Class 1) accuracy, making it ideal for energy audits, monitoring photovoltaic systems, or managing critical loads in homes and commercial premises.

• 80A capacity: With a maximum current rating of 80A, it is ideally sized for the main circuits of flats, single-phase houses or for individual monitoring of high power appliances (heat pumps, EV charging stations).

• Compact and Robust: The small dimensions allow the clamp to be installed even in crowded switchboards where space on the rail or between cables is limited.

• Bidirectional Monitoring: Able to measure the flow of energy in both directions, it is essential for prosumers who want to monitor both grid consumption and the surplus injected by solar panels.

Examples of Use

1. General Consumption Monitoring: Install the clamp on the main power phase to view real-time whole-house consumption in the Shelly Smart Control app.

2. Photovoltaic Systems: Use one clamp to measure inverter output and the second clamp (on the Shelly EM) to measure home consumption, getting a complete picture of energy efficiency.

3. Overload Protection: Monitors current on a dedicated circuit and configures the Shelly EM to shut off non-critical consumers if the 80A threshold is close to being reached.

Why choose Shelly 80A Clamp with Connector?

It's the missing piece for professional power monitoring. Unlike universal clamps, this model is calibrated specifically for Shelly Generation 3 hardware, eliminating reading errors and providing a secure mechanical connection that won't loosen over time due to switchboard vibration.
