Product Description
Dold BD9080.12/61
The Dold BD9080.12/61 is a versatile multifunction measuring relay from the VARIMETER PRO series, designed for comprehensive monitoring of 3-phase AC mains. It reliably detects and signals various network faults, including overvoltage, undervoltage, incorrect phase sequence, phase failure (even with regenerated voltage), and asymmetry. Featuring an LCD display for easy visualization of measured values and parameters, the BD9080.12/61 offers adjustable thresholds and time delays to prevent nuisance tripping. This model, with its specific /61 variant features (requiring an AC 230V auxiliary supply), is suitable for demanding industrial applications requiring precise and dependable mains protection to safeguard equipment and ensure operational continuity.
