SYLVANIA T77U031 Contactor

The SYLVANIA T77U031 Contactor is a 3-pole AC magnetic switch rated for 30 A at up to 600 VAC, designed for use within TM motor-control systems. This NEMA Size 1 contactor from the Sylvania/Joslyn Clark lineage is intended to energize and de-energize motor circuits with a compact footprint suitable for panel-mounted control gear in industrial environments. Models in the T77U031 family are documented in catalog references as TM-type contactors capable of handling three-phase loads and typically shipped with a normally open control-circuit contact, making them compatible with standard local control circuits. While coil voltages and exact horsepower ratings vary by coil configuration and voltage, the T77U031 designation corresponds to the 30 A, 600 VAC TM-contactor variants documented in Joslyn Clark/Sylvania motor-control catalogs. Applications span general-purpose motor control in machines and conveyors, pumps, fans, and other industrial equipment where reliable switching of AC loads up to 600 V and 30 A is required, with mounting designed for standard control panels.
