Current Transformer Shelly 50A 11mm Conductor Diameter

The Shelly 50A current transformer scales high primary currents to standardized, low secondary currents for safe and accurate measurement. It delivers a secondary current accurately proportional to the primary conductor's current while presenting a negligible load to the primary circuit. The transformer has a compact clamp design with an 11 mm conductor diameter compatibility and a 60 cm cable length.

Advantages

The Shelly 50A CT provides precise proportional current output suitable for Shelly monitoring devices, a compact clamp that fits conductors up to 11 mm, and minimal impact on the primary circuit. Its 60 cm cable allows flexible placement relative to connected equipment.

Suitable for

• Energy and load monitoring in residential and small commercial electrical installations
• Integration with Shelly energy monitoring devices and smart relays
• Retrofitting existing installations where conductor diameter does not exceed 11 mm

How to use

Open the clamp and place it around the live conductor (single-phase or individual phase conductor) ensuring the conductor sits centrally inside the clamp. Close the clamp until it locks. Connect the CT secondary cable to the corresponding input on the Shelly device or compatible meter following the device's wiring diagram. Verify polarity if required and secure cables to prevent strain on the connector.

Usage recommendations

Use the CT only on conductors with diameter up to 11 mm and within the rated 50 A primary current. Do not clamp around multiple conductors simultaneously. Ensure all wiring and installation comply with local electrical regulations and, if uncertain, have a qualified electrician perform the installation.
