Siemens 3TY4803-0AK6 Coil Kit 120 60Hz 110V 50Hz

Siemens 3TY4803-0AK6 Coil Kit is a dual-voltage magnet coil designed to energize a range of Siemens contactors, operating on 120 V AC at 60 Hz or 110 V AC at 50 Hz to accommodate different regional power systems. This coil is specified for use with Siemens contactor families including 3TF30-33, 3TF40-43, 3TH3, 3TH4, 3TB40-44, 3TC44, and 3TH8, providing a versatile replacement option in control panels and industrial automation setups. When the coil is energized with the appropriate AC voltage, it generates the magnetic field that pulls in the contactor armature, closing the main contacts and enabling upstream equipment such as motors, pumps, or conveyors to start. The part is documented as interoperable with cross-reference coils such as 3TY7403-0AK6, supporting installation in legacy systems where this exact coil model was originally specified. In practice, this Siemens coil kit helps maintain reliability in motor-control circuits by matching the voltage-frequency requirements common to North American and European facilities while preserving compatibility with the associated contactor hardware.
