Shelly Split-Core 50A - Current transformer, Black

The Shelly 50 A split-core current transformer monitors electricity usage and power generation on single-phase circuits. Rated for a maximum of 50 A, it is suitable for standard domestic or light commercial electrical loads. Its split-core design allows the sensor to open and clamp directly onto an existing wire, enabling installers to add metering without disconnecting the main conductor. The device tracks power flow in real time.

Data collected by the transformer is processed by a compatible Shelly EM module. Users can view energy statistics and integrate these metrics into home automation setups. The ferrite core ensures stable signal induction, and the black casing remains unobtrusive when mounted in electrical panels. An 11 mm internal diameter provides sufficient clearance to fit standard insulated cables.

• 1% measurement accuracy: provides reliable data for consumption tracking.
• 20 Ω input impedance: ensures stable performance during continuous monitoring.
• 23.5 x 41.5 x 26 mm: compact size for use in crowded junction boxes.
• Tool-free clip-on design: allows for installation without modifying existing wiring.
