The W2-S70 split-core measuring current transformer is part of Bender W series, perfectly compatible with Bender RCM residual current monitors and EDS insulation fault locators. It converts AC and pulsed DC residual leakage current into weak measuring signals at a ratio of 600:1 for continuous leakage monitoring and fault early warning. The splittable core enables quick retrofitting without cutting power cables for new and old distribution cabinets. Built-in secondary winding overvoltage protection supports up to 40 meters wiring distance between transformer and evaluation unit. The 70mm large inner diameter accommodates multiple power cables with reliable long-term measurement performance.
