Product Introduction

The Shelly 80A Clamp is a split-core current transformer designed to measure electrical current when used with Shelly energy monitoring devices such as the Shelly EM Gen3. The clamp installs around an electrical conductor to measure current flow safely without requiring direct electrical contact or modifications to the wiring.

By converting large electrical currents into smaller standardized measurement signals, the clamp enables the Shelly EM Gen3 to accurately track real-time energy consumption through the Shelly Smart Control platform or compatible smart home systems.

Its split-core design allows the clamp to open and close around an existing cable, making installation simple and non-intrusive. This makes the Shelly 80A clamp ideal for monitoring power usage of appliances, circuits, or entire sections of a building’s electrical system.
