Professional split-core current transformer SCT-013 designed for non-invasive AC current measurement. Perfect integration with RBgrid SDK and RBgrid App. The transformer clips around a single wire without breaking the circuit, providing safe and convenient current monitoring for existing installations. Connects via SCT adapter module (sold separately).

Connection
Physical Installation:
- Open the transformer core using the clip mechanism
- Place around a single current-carrying wire (L or N, not both)
- Ensure complete closure for accurate readings
- Orient according to arrow marking for correct polarity
IMPORTANT:
- Measure only ONE conductor (L or N), never both
- Use appropriate 3.5mm jack adapter module with built-in conditioning circuit
Software Integration
Configuration via RBgrid Web App:
- Navigate to Sensors configuration page
- Select "SCT-013" and choose your model variant
- Specify the GPIO pin connected to adapter output
