Bender B911733 W3-S105 Measuring Current Transformer

The Bender B911733 W3-S105 measuring current transformer is a circular-core current transformer with a 105 mm (ø105) window, designed to sense conductor current and provide a proportional secondary signal to Bender monitoring equipment. Identified in Bender’s W-series data as the W3-S105 model and catalog number B911733, this unit is listed as an alternative measuring current transformer for EDS systems and is referenced in Bender documentation alongside RCMS residual current monitors. This compact, 105 mm window CT is typically employed in electrical safety and protection applications where current measurement is fed into Bender RCMS monitoring devices or EDS safety systems, enabling accurate current sensing for protection, leakage monitoring, and diagnostic workflows without relying on external measurement interfaces.
