Product Overview
The BetaSet 49T/4 is a Stage IIIA compliant 4‑pole marine generator designed for vessels operating in regulated inland waterways such as the Rhine. Based on a high-capacity, electronically governed 3,769 cc diesel engine, the unit provides reliable output from 40 to 52 kVA. Suitable for continuous use, it is offered with heat exchanger, keel, or radiator cooling, and is optimized for boats under 20 meters in length operating under CCNR rules.
