TB135-1 is a 110/120 VAC coil for Clark/Sylvania TB-series contactors and starters, used to energize the coil so the main contacts close. This GTE Sylvania coil is designed for 50/60 Hz electrical systems and is commonly employed in industrial motor-control circuits to switch heavy loads via a contactor. Typical applications include pumps, conveyors, and fans where an existing TB135-1 coil is replaced or a compatible replacement is required. It serves as a coil accessory for TB-series control devices, not a standalone relay module.
