WAGO 855-2701/064-001 Split-Core Current Transformer 64 A / 1 A, Black

The WAGO 855-2701/064-001 is a high-quality split-core current transformer designed for accurate measurement of alternating currents up to 64 A. With a secondary output of 1 A and a transformation ratio of 64:1, this transformer is ideal for energy monitoring, power metering, and industrial automation applications. Its split-core design allows for easy installation without disconnecting the primary conductor, making it perfect for retrofitting existing systems.

Advantages

Easy installation thanks to split-core design; high accuracy class 1 ensures reliable measurement; compact dimensions (27 mm x 23 mm x 46 mm) save space; robust polyamide housing provides durability; CAGE CLAMP® connection technology for secure and maintenance-free wiring.
