Product information

Description

The Shelly 120 A current transformer is a high-precision sensor engineered for accurate energy monitoring and electrical consumption tracking. Designed to integrate seamlessly with compatible Shelly energy metering devices, this component allows users to monitor power usage in real-time. By scaling high primary current values into standardized, measurable secondary currents, it ensures reliable data acquisition without interfering with the primary electrical circuit.

Advantages

This current transformer offers exceptional precision in energy measurement, providing data that is directly proportional to the current flowing through the monitored line. Its compact design and 17 mm conductor diameter make it versatile for various installation environments, ranging from residential smart home setups to industrial monitoring systems. The device is built to be durable and reliable, ensuring consistent performance over time while maintaining a negligible load on the electrical circuit it monitors.

Suitable for

  • Smart home energy management systems
  • Industrial power consumption monitoring
  • Real-time electrical load analysis
  • Residential energy efficiency tracking

When it may not be suitable

This sensor is specifically designed for use with compatible Shelly energy metering hardware and may not function correctly with third-party monitoring systems. It is not intended for use with high-voltage systems exceeding its specified nominal current capacity or for applications requiring non-standard measurement protocols.

Key specifications

  • Nominal current output: 120 A
  • Conductor diameter: 17 mm
  • Cable length: 60 cm
  • Dimensions: 31 mm x 45 mm x 30 mm
  • Colour: White

How to use

To install the Shelly 120 A current transformer, clamp the sensor around the primary conductor of the electrical circuit you wish to monitor. Ensure the sensor is securely closed and connected to the appropriate input on your Shelly energy metering device using the provided 60 cm cable. Once connected, configure the device through the Shelly interface to begin receiving accurate energy consumption data.

What to consider before purchase

  • Verify compatibility with your existing Shelly energy metering device
  • Ensure the conductor diameter of your electrical cable does not exceed 17 mm
  • Confirm that the circuit current does not exceed the 120 A nominal rating

Usage recommendations

Always ensure that the main power supply is disconnected before installing or handling the current transformer to prevent electrical hazards. Ensure the sensor is fully closed around the conductor to maintain measurement accuracy.
