Frequently asked questions
What are the full technical specifications of the Siemens 3RT1054-1SF36-3PA0?
Engineers must confirm voltage, current, coil range, and auxiliary contact config match panel design before BOM release.
What does the -3PA0 suffix mean on Siemens 3RT1054 contactors?
Decoding the suffix prevents ordering the wrong coil, terminal, or PLC-input variant.
Can the 3RT1054-1SF36-3PA0 be controlled by a 24V DC PLC output?
F-PLC input compatibility determines whether the contactor can be driven directly from a PLC sink/source output.
Is the 3RT1054-1SF36-3PA0 suitable for AC-3e operation at 55 kW / 400 V?
AC-3e duty rating validates use in modern IE3/IE4 motor switching applications per IEC 60947-4-1.
What is the current price and distributor stock for 3RT1054-1SF36-3PA0?
Buyers need live pricing and authorized stock to authorize purchase and avoid counterfeit risk.
What is the cross reference or replacement for 3RT1054-1SF36-3PA0?
Identifies equivalent or successor part numbers when the exact MPN is unavailable or obsolete.
