Sylvania TB171-2 Relay and Timer Coil

The Sylvania GTE TB171-2 Relay & Timer Coil is a 220–240V AC coil designed to energize timer-relay assemblies in electrical control circuits. This component serves as the coil portion of timer-relay configurations, enabling timed control within equipment and control panels. With a nominal 220–240V coil rating, TB171-2 is suited for standard mains voltages in regions that use 230V systems and is intended to be used with compatible timer-relay hardware to deliver timed switching actions. Its role is to actuate the timer function when energized, enabling sequences, delays, or timed enable/disable operations in appropriate applications. The TB171-2 designation identifies a specific coil configuration used in SYLVANIA/GTE timer-relay variants, so verifying compatibility with your timer base or chassis before installation is advisable.
