유지보수 노트
When procuring spare parts for legacy units, always verify the complete type designation plus serial number from the nameplate; do not rely solely on the order number.
The 3TL61 series uses an economy holding resistor for the coil. Do not remove it during servicing.
Main-circuit resistance shall be ≤ 280 μΩ; measurement is mandatory during overhaul.
The auxiliary switch is positively-driven. Do not substitute with standard auxiliary contacts.
If you have a nameplate photo, I can help verify full compatibility. I can also compile dimension comparison tables for 3TL61 and 3TM33.
