Main Switchboard (MSB) · Power Distribution
Schneider Electric Marine Okken Marine Plus 1000A 440V IP54 is listed as a Main Switchboard (MSB) within the Power Distribution category. It is typically installed in the main or emergency electrical switchboard room, connected to generators, transformers and shipboard distribution feeders. Its engineering role is to receive, protect, synchronize and distribute electrical power to vessel consumers. The complete model designation should be retained when matching drawings, certificates, service information and spare parts because neighboring variants may differ in configuration even when they share the same equipment family. The exact shipboard arrangement and interfaces remain installation-specific and should be checked against the vessel’s approved drawings and equipment documentation. Where an operating value, tolerance, wear limit or setting is not explicitly stated in the source data, refer to the manufacturer documentation for the exact figure.
Every value below comes from the manufacturer datasheet or class-society record on file for this model.
