Siemens 3TY6483-0AM0 Coil

Siemens 3TY6483-0AM0 is a replacement magnet coil for Siemens/Furnas contactors 3TB47, 3TB48 and 3TC48. The coil is an alternating current (AC) coil rated for 220–240 V at 50 Hz and 264–276 V at 60 Hz, enabling operation across common industrial power standards. This 3TY6483-0AM0 variant is used to actuate the contactor's magnetic armature when control voltage is applied, enabling switching of downstream loads such as motors, pumps, conveyors, or HVAC equipment. It belongs to Siemens' 3TY6483 family of magnet coils, with voltage variants designed to match different supply frequencies; the 60 Hz rating maintains 264 V nominal in many regions, while the 50 Hz rating aligns with 230 V nominal. This coil is typically supplied as a coil kit to retrofit existing equipment, providing a direct fit for compatible contactors and preserving original control characteristics. For correct replacement, confirm the target contactor model (3TB47, 3TB48, or 3TC48) and the system frequency to select the proper voltage variant. Note that 3TY6483-0AM0 is part of Siemens Furnas' legacy line of coil parts and is intended for industrial environments where reliable control of motor loads is required.
