JRCS JSB-2L: Compact Low Voltage Switchboard for Marine Power

The JSB-2L is a compact Low Voltage Main Switchboard developed by JRCS, known for its exceptional quality and reliability. Compared to older models, this one boasts a 33% reduction in size while simultaneously maintaining performance and reliability. Despite its reduced size, the JSB-2L maintains easy cable access and employs vertically placed generator bus bars to support its compact form.  The new design, which was made in collaboration with the Air Circuit Breaker (ACB) manufacturer, employs the most up-to-date miniaturisation technology.  With the new JSB-2L design, the control circuits, operation switches, and indication lamps are now combined into single units for streamlined maintenance.

  • Downsized design enables significant space saving

  • A combined unit of switches and indicator lamps simplifies maintenance

  • Use of detachable terminal blocks enhances replacement ease

  • Integrated bus bar separation device allows safe and simple operation
