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

Evelyn ★★★★★

The accuracy on these is spot-on—the secondary output stayed perfectly proportional even when I pushed 40+ amps through the primary. Compact enough to fit in my crowded panel, and the clamp locks securely without any wobble.

Matthew ★★★★★

Been using this clamp to monitor my workshop's main feed and the secondary output is dead on compared to my multimeter readings. The 50A rating gives me plenty of headroom for the occasional spike, and the clamp opens wide enough to fit over thicker cables without a struggle.

Ava ★★★★★

Had to redo a couple of wiring runs in my panel, and this clamp made it trivial to verify the secondary current matches the primary exactly—the ratio held steady even under a heavy load. Fits nicely on the busbar without any awkward bending, and the terminal block feels solid for the price.
