INSLTR-SCRND T101B (SM0644)

Intermatic #

124T1954

The Intermatic 124T1954, also referenced as SM0644, is a screened insulator built specifically for the T101B time switch in its independent motor wiring configuration. This insulator fits inside the T101B housing to separate the live switching contacts from the timer motor wiring and other internal components. Because the T101B's independent motor wiring arrangement differs from the standard wiring on related time switch models, this insulator is matched to that specific configuration rather than being interchangeable with insulators for other Intermatic time switches. A technician replaces this part when the original insulator in a T101B unit has cracked or otherwise failed. As a listed service part, the 124T1954 supports repair of an existing T101B time switch rather than being supplied with a new unit.
