The manufacture of the mechanically interlocked reversing contactor used throughout the industry in commercial operators, and in Allstar commercial operators, has discontinued production of their MMT104-NX28 device.  The replacement part is the 100-C16*10 reversing contactor.

While functionally and electrically identical, the "100-C" is slightly larger than the "MMT104" and the mounting hole pattern is different and the required changes are incorporated into all new production.  However, field replacement of the "MMT104" with the "100-C" will require repositioning of the reversing contactor in the control box and drilling new mounting holes.

Effective August 27th, 2001 (serial numbers starting with 3601), all Allstar commercial operators that require reversing contactors will be built with the "100-C" reversing contactor.  Operators built prior to this date, using the "MMT104" reversing contactor, may still be in stock and will be use as required to fill orders.
