Sylvania T13U034 TM NEMA Size 4 Industrial Motor Starter

Sylvania T13U034 TM NEMA Size 4 Industrial Motor Starter is a 3‑pole motor starter from the TM family designed to control large three‑phase motors with a 120 VAC coil and a 135 A rating. It belongs to the NEMA Size 4 class of Type TM starters, a configuration cataloged under Bulletin 6013 TM for industrial use where remote start/stop control is required. Within the T13U034 family there are coil‑voltage variants—open‑type entries such as T13U034‑46 list a 440–480 V coil, while 120 V coil versions (for example, T13U034‑76) are referenced in catalogs and listings—demonstrating voltage flexibility within the line. The model designation places the unit in the Joslyn Clark/Sylvania lineage of industrial control gear, reflecting its role in robust motor control applications in factory and process environments. In practice, this starter is used to initiate and terminate power to large three‑phase motors in demanding industrial settings, where a 135 A, 120 V coil device is suited to switching substantial loads with reliable operation.
