JRCS JSB-2 Medium Voltage Switchboard for Marine & Offshore Applications
The JSB-2 Medium Voltage Switchboard is a compact, metal-enclosed system designed by JRCS for marine applications. Engineered with advanced 7.2kV technology and standard short circuit capacity of 25kA (optional 40kA), it ensures operational efficiency and system intelligence through its remote control and monitoring interface. Its structure includes separate compartments for breakers, bus bars, high and low voltage cables, enhancing safety and organization. The system integrates earthing switches and mechanical interlocks, along with electromagnetic locking options for access control. Built to withstand marine environments, it features insulation rated at 28kV and optional gas pressure relief ducts. Fully compliant with IEC 62271-200 and certified by multiple classification societies, JSB-2 provides reliable and safe power distribution.
Compact design achieved by structural downsizing
Enhanced safety via earthing switches and mechanical interlocks
