High-accuracy current transformer (split-core) | Ø16 mm | 5 A | 25 mV | 2 m cable | ASCT-16
Code: ESASCT-16High-accuracy split-core current transformer (CT) designed for reliable alternating current (AC) measurement in electrical and automation systems. The split-core design allows the transformer to be installed without disconnecting the cable, making it especially convenient for modernization, diagnostics, and energy metering projects. Thanks to multiple available input/output ratios and precise signal conversion, the transformer is widely used with energy meters, power analyzers, PLC, BMS, and EMS systems.
