CARLO GAVAZZI Automation Components Three Phase Starter for Scroll Compressors RSBT Series

RSBD and RSBT are easy to use soft starters for scroll compressors up to 45Amp (RSBD) and 32Amp (RSBT) nominal current. The units are equipped with a patented auto-adaptive algorithm that automatically adapts itself to the specific compressor it is controlling ensuring that an optimum inrush current reduction is achieved. RSBD is a 2-phase controlled solution and RSBT is a 3- phase controlled solution. RSBD and RSBT are internally bypassed resulting in less heat dissipation inside the panel. Short Circuit and Overload protection are not provided with the controller and must be procured separately.
