Siemens 3UA5200-1F U 3.2 - 5A 600V 3P Contactor

Siemens 3UA5200-1F U is a bimetal thermal overload relay from the 3UA5 family that mounts to Siemens 3TF32/33 three‑pole contactors to protect 3‑phase motors in up to 600 V circuits. It features a user‑settable current range of 3.2 to 5 A and includes 1 normally open and 1 normally closed auxiliary contact for signaling or interlocking in the control circuit. This manual‑reset device is designed specifically for contactor mounting and is compatible with 3TF32/33 assemblies, delivering protection through a time‑delayed trip and requiring deliberate reset after an overload. Siemens lists the 3UA5200-1F U as no longer available in its official catalog, indicating the model has been discontinued; customers seeking current availability should consult distributors for alternatives or newer compatibility.
