Product information

Description

The Shelly 50A Black split-core current transformer is designed to measure alternating current up to a nominal 50 A. Finished in black, the CT provides a proportional secondary output suitable for integration with energy monitoring devices and data loggers. Its split-core design allows for quick installation around an existing conductor without disconnecting wiring, making it convenient for retrofit and new installations in residential and light commercial electrical systems.

Advantages

The split-core construction enables tool-free clamping around live conductors for fast, low-disruption installation. The transformer gives a stable proportional output for accurate current sensing when paired with compatible monitoring equipment. Compact dimensions and durable housing provide space-saving mounting and protection against everyday mechanical stress. The black finish blends unobtrusively with electrical panels and wiring runs.

Suitable for

  • Monitoring individual circuit loads in homes and small businesses
  • Integration with energy meters, data loggers, and smart energy controllers
  • Load profiling and preventive maintenance checks
  • Retrofit installations where conductor disconnection is impractical

Key specifications

  • Nominal primary current: up to 50 A (AC)
  • Split-core design for clamp-on installation
  • Secondary output: proportional to primary current (for connection to compatible monitoring devices)
  • Housing color: black
  • Compact form factor suitable for panel or DIN-rail adjacent placement
  • Intended for single-conductor measurement

How to use

Open the split-core CT and place it around a single live conductor; ensure it fully closes and the core latches securely. Connect the secondary output leads to the input terminals of the monitoring device or meter according to that device's wiring and polarity requirements. Verify that the monitoring equipment is configured for a 50 A primary range or the appropriate transformation ratio to display correct current or power values. After installation, check connections and readings for consistency before leaving the system in continuous operation.

Usage recommendations

Use the CT only on single conductors (not on multi-core cables) and within its rated primary current. Ensure the secondary is never left open-circuited while the primary is energized. Match the CT output to compatible input impedance and scaling settings of the monitoring device for accurate measurements.

Product comparison

The Shelly 50A Black current transformer is compared with two alternative energy monitoring devices from the same manufacturer: the Shelly EM+50A and the Shelly Pro EM 50A. All three products are designed for electrical circuits carrying up to 50 A in residential and light commercial installations. The main practical difference is that the Shelly 50A Black is a standalone component (a split-core current transformer), whereas the Shelly EM+50A and Shelly Pro EM 50A are complete measuring devices that combine sensors and measurement units for energy monitoring and remote management.

⚙️ The specification comparison covers the device type, maximum measurable current, system components, and integration scenarios.

This comparison demonstrates that the Shelly 50A Black is a specialized component (current transformer), while the Shelly EM+50A and Shelly Pro EM 50A are full energy monitoring devices. Choose the Shelly 50A Black if you specifically need a standalone sensor for an existing system. Opt for the EM models if you require a complete unit for data collection, energy tracking, and system integration.
