Transformer current transducer TAA-01005-3637

DIN railsplit-coreprecision

The TA-3637 split core current transformers are precision class 0.5 components designed for easy installation. Suitable for current measurement on both cable and busbar systems, they are ideal for use with network power meters, energy counters, and electrical measurement converters. These transformers reduce line current to a secondary circuit value of up to 5 A.
