Sylvania TB159-1 Relay Coil Assembly

TB159-1 is an OEM relay coil assembly for Joslyn Clark/Sylvania TM-series contactors (NEMA sizes 00, 0, 1 and 2), designed to be a direct replacement coil that energizes the magnet to pull in the contacts. The coil is rated for 110–120 V AC operation and supports 50 Hz and 60 Hz frequencies, ensuring compatibility with standard North American electrical systems and many international installations. The unit weighs about 0.68 kg, indicating a compact, lightweight coil suitable for integration into existing TM-series starters without adding significant bulk, while preserving mounting compatibility with standard coil hardware. This TB159-1 coil is intended for use with TM contactors when replacing an original coil to restore control of the motor load, and is commonly referenced as the OEM coil for Sylvania Joslyn Clark equipment, making it a true drop-in replacement for maintaining system performance.
