Product description

The Allen Bradley 100-MCA00 is a mechanical interlock accessory designed to be used with Allen-Bradley 100-C series contactors (excluding 100-C40 and 100-C90). This accessory ensures that two contactors cannot be energized simultaneously, preventing unsafe operating conditions and protecting equipment. It typically includes a 100-S9 connector and does not feature auxiliary contacts.

This mechanical interlock is vital in applications requiring non-overlapping operation of two contactors, such as reversing motor starters or specific interlocking schemes in automation systems. It provides a physical mechanism to ensure sequential operation.
