GUANDO SCT-013 Split Core Current Transformer — Non-Invasive AC Current Sensor

Accurately measure AC current without cutting or interrupting your existing wiring. The GUANDO SCT-013 Split Core Current Transformer is a compact, non-invasive sensor designed for energy monitoring projects, home automation systems, and power measurement applications. Simply clamp it around a single conductor and start reading current in real time — no rewiring required.

Compatible with popular open-source energy monitoring platforms including OpenEnergyMonitor and similar DIY power-monitoring projects, this sensor is an ideal building block for smart home energy dashboards, IoT power loggers, and maker electronics builds.

Key Features

  • Non-Invasive Design: Split-core clamp opens and closes around a conductor — no circuit interruption needed.
  • Multiple Current Ranges Available: 5A, 10A, 20A, 30A, 50A, 60A, and 100A variants to suit a wide range of applications.
  • Model Options: SCT-013-000 (0–100A, voltage output), SCT-013-030 (0–30A), SCT-013-050 (0–50A).
  • Ferrite Core: High-permeability ferrite core for accurate and stable current measurement.
  • Standard 3.5mm Output Plug: Plug directly into a microcontroller ADC input (e.g., Arduino, Raspberry Pi) with no additional adapters.
  • Wide Opening Size: 13 × 13 mm conductor aperture accommodates most standard single-core cables.
  • High Dielectric Strength: Rated at 6,000V AC / 1 min for reliable electrical isolation.
  • Flame-Retardant Housing: UL94-V0 rated plastic enclosure for safety in enclosed electrical environments.
  • Long Cable Lead: 1.5 m cable for flexible positioning away from the measurement point.
  • Wide Operating Temperature: Functions reliably from −25°C to +70°C.

Frequently Asked Questions

Q: What is the difference between SCT-013-000, SCT-013-030, and SCT-013-050?

A: The SCT-013-000 is a 0–100A model with a voltage output (0–1V), while the SCT-013-030 measures 0–30A and the SCT-013-050 measures 0–50A — both with a built-in burden resistor for direct voltage output via the 3.5mm plug. Choose the model that best matches the maximum current draw of the circuit you want to monitor.

Q: Do I need to cut or splice my wiring to use this current transformer?

A: No — that's the key advantage of a split-core design. Simply open the clamp, place it around a single conductor (live OR neutral, not both), and close it. The transformer inductively senses current flow with zero contact with the live conductor, making installation safe and straightforward.

Q: What microcontroller or platform can I use with the SCT-013 sensor?

A: The SCT-013 series works with any platform that has an analog input pin, including Arduino, ESP8266, ESP32, and Raspberry Pi (with an ADC). It is officially supported by the OpenEnergyMonitor project and is compatible with the emonLib library for easy integration into energy monitoring sketches.

Q: Is this sensor safe to use in an electrical panel or breaker box?

A: The SCT-013 features a dielectric strength rating of 6,000V AC (1 min) and a UL94-V0 flame-retardant housing, providing robust electrical isolation between the measured conductor and the output circuit. Always follow local electrical codes and safety guidelines when working inside electrical panels.
