Used, good working condition removed from a functioning installation.
Housing and terminals show normal signs of use: dust, minor discoloration and cosmetic scuffs; no visible cracks, broken parts, or signs of overheating on terminals or contact chambers.
Coil and mechanism actuate correctly when operated manually; auxiliary block and terminal covers are intact.
Heavy‑duty contactor suitable for large three‑phase motors or power distribution where a 110 A / 600 V contactor is required, when paired with appropriate overload protection and fusing according to Siemens data.
Coil voltage and any special options (e.g. surge suppressor on coil) should be confirmed from the close‑up coil label visible in the listing photos before ordering; replacement coils for 3TF50 are available under the 3TY75… series if needed.
