Overview Chevron DownChevron Down

Our Bulletin 141 Modular Control System (MCS) Mounting Systems provide several different mounting solutions for IEC loadfeeders. Factory-assembled Bulletin 103 Non-Reversing and Bulletin 107 Reversing starters are available for these mounting solutions. 

 

Our 141A mounting systems include preconfigured circuit breaker modules for feeding and protecting a busbar system. For applications up to 100 A, we offer the 141C CrossBoard System, a true plug and play system with touch-safe plastic housing, components simply snap onto the CrossBoard without tools, meaning the connection is automatic. Components can be easily removed and snapped back on to other sections of the CrossBoard.

 

The CrossBoard system helps keep panels clean, organized and compact with a large reduction in power wiring.
