The Weidmüller RCMA-B22-D175-1.5 is a Rogowski rope current transformer designed for accurate AC current measurement on conductors up to 175mm in diameter. Unlike traditional wound current transformers, the flexible rope design clips around an energised conductor without disconnecting the primary circuit — making it ideal for retrofitting into existing switchboards, substations, data centres, and commercial buildings. The 1.5m cable connects to the RCMC-5000-1A-P transducer, which converts the Rogowski signal to a standard 0–1A AC output compatible with any energy meter that accepts a 1A CT input.
