GEAFOL Marine 160kVA 690/400V

Siemens Marine GEAFOL Marine 160kVA 690/400V is a shipboard unit in the Transformers group, classified in the source as Marine Transformer (Dry/Cast-Resin). It is normally installed in electrical rooms, propulsion switchboard spaces or dedicated transformer compartments with adequate ventilation. Its primary duty is to convert shipboard AC voltage levels and provide isolation where required for distribution or equipment supply. In service it interfaces with upstream switchgear, downstream distribution boards, protection devices, temperature monitoring, ventilation and earthing. Compared with neighboring entries in the same product family, this record is the exact Siemens Marine GEAFOL Marine 160kVA 690/400V variant; the model designation should be retained unchanged when matching onboard documentation and spares. For exact limits, settings, test values and approved maintenance criteria, refer to the manufacturer documentation for the exact figure.
