Category: Energy meters

Current transformers scale the large values of current to small, standardized values for measuring purposes. They provide a secondary current that is accurately proportional to the current flowing in its primary circuit. The current transformer presents a negligible load to the primary circuit. 

The length of the CT clamp's cables is 60 cm. 

*NOT compatible with Shelly Pro EM-50, Shelly Pro 3EM, Shelly EM Gen3,Shelly EM Gen4 and Shelly Pro 3EM-3CT63

Ruby V. ★★★★★

It’s so reassuring to see the secondary current stay proportional to the load like it should, and the clamp housing feels solid enough to leave in place for years. I checked it against my bench meter across a few loads and the scaling held up impressively well.

Emma ★★★★★

Ratios are dead-on across a range, and I love that the secondary output scales so cleanly with the primary load. Mounted it in my panel and the readings match my standalone meter within a few percent. Exactly what I needed for accurate energy logging.

Amelia ★★★★★

The scaling is spot-on compared to my old meter, and the clamp fits snugly around my 100A feed. Hooked it up in five minutes, zero drift so far.
