Shelly 50A CLAMP EM GEN3

Product Introduction

The Shelly 50A Clamp EM Gen3 is a split-core current transformer designed to measure electrical current in conjunction with the Shelly EM Gen3 smart energy meter. The clamp is placed around a live electrical conductor to measure current flow without requiring direct electrical contact, enabling safe and accurate energy monitoring.

When connected to the Shelly EM Gen3 module, the clamp allows users to track electricity consumption of individual circuits or appliances in real time through the Shelly Smart Control platform or compatible automation systems. This makes it ideal for monitoring household circuits, specific appliances, or sections of a building’s electrical system.

The clamp’s split-core design allows it to open and close around an existing cable, making installation simple without disconnecting wiring. With accurate current measurement and compact construction, it is commonly used for energy monitoring installations inside electrical distribution boards.

Key Features
