Current Transformer Shelly 096-8354 Black 120 A

The Shelly 096-8354 Black 120 A current transformer is a compact clamp-style device for measuring alternating currents up to 120 A. Its small footprint and 17 mm conductor opening make it suitable for installation around a single conductor in distribution boards, meters, or control cabinets. The unit includes a 0.6 m cable for connection to monitoring equipment and is rated for a nominal input voltage of 3000 V to ensure electrical isolation and safe operation in typical low-voltage distribution environments.

Advantages

The Shelly 096-8354 offers a combination of compact size and sufficient current range for residential and light commercial applications. Its black housing and modest dimensions allow discrete mounting even in confined spaces. The 0.6 m cable simplifies routing to measurement inputs, while the 17 mm conductor diameter supports compatibility with many single-core conductors. A nominal input voltage rating of 3000 V provides electrical isolation characteristics appropriate for safe measurement tasks.

Suitable for

• Measuring load current on single conductors in distribution panels
• Energy monitoring systems and third-party meters requiring CT input
• Smart home power management and load balancing
• Temporary current measurements during commissioning or troubleshooting

Key specifications

• Maximum measurable current: 120 A

• Cable length: 0.6 m
• Nominal input voltage (isolation rating): 3000 V
• External dimensions (W × D × H): 31 mm × 30 mm × 45 mm
• Color: Black

How to use

Open the clamp and place a single live conductor through the 17 mm aperture, ensuring the conductor is centered for consistent measurement. Close the clamp securely and route the 0.6 m cable to the appropriate current input of the monitoring device, observing correct polarity and input impedance requirements of the connected instrument. Verify that the installation environment and wiring meet the nominal input voltage rating and safe working clearances. Perform a calibration or scaling step in your monitoring system if required to match the CT's transformation ratio.

Usage recommendations

Use the transformer only on single conductors that fit the 17 mm aperture and avoid clamping around bundled or multi-core cables. Ensure connections to monitoring devices are made with appropriate safety precautions and that the nominal input voltage and isolation requirements are respected. For accurate long-term measurements, avoid mounting the CT near strong magnetic sources or equipment causing excessive vibration.
