Osram Sylvania TB113-2 Magnet Coil 110 120V AC

Osram Sylvania TB113-2 magnet coil is a 110–120 V AC control coil used in vintage magnetic starters and related control assemblies within the Sylvania/Joslyn Clark family. It is specified for 50 Hz operation at 110 V and 60 Hz operation at 110–120 V, enabling compatibility with both European/Asian and North American power systems where 50 Hz or 60 Hz service is present. Often found as new old stock (NOS), this coil carries the 110–120 V input rating that drives the magnetic field to actuate the associated contact set. In operation, energizing the coil closes the magnetic switch in the starter circuit, allowing current to flow to a connected contactor or relay to control a machine or motor. This TB113-2 variant is typically used as a replacement coil in legacy equipment within industrial control panels that rely on 110–120 V AC coils, so it’s important to match the TB113-series footprint and terminal layout with your existing hardware for a reliable fit.
