100-MCA00 Applications
The 100-MCA00 is a mechanical interlock accessory that links two Bulletin 100-C, 104-C, 700-CF, or 700S-CF contactors so they cannot close simultaneously. It is essential in reversing motor starters and other applications where two contactors must never energize together, preventing short circuits and mechanical conflict. Mounted between a contactor pair, it provides purely mechanical interlocking with no auxiliary contacts, complementing electrical interlock wiring for safe forward/reverse and multi-speed motor control schemes.
