Frequently asked questions
What does the MPN 3RT1054-1AV36 mean?
Buyers and specifiers must decode the Siemens Sirius 3RT10 ordering code to confirm frame size, coil, and terminals match their BOM.
What is the coil voltage of the Siemens 3RT1054-1AV36?
A wrong coil voltage (380-420 V AC/DC) will not engage the contactor and can void the panel build.
Is the 3RT1054-1AV36 suitable for AC-3e applications?
Modern IEC motor starters require AC-3e-rated devices; confirming 115 A AC-3e compliance protects the motor warranty.
What is the difference between 3RT1054 and 3RT1056 contactors?
Engineers frequently cross-reference sibling part numbers to right-size motor switching devices and avoid overpaying.
How many auxiliary contacts does the 3RT1054-1AV36 have and what type are they?
Knowing the 2 NO + 2 NC layout is critical for wiring interlock, feedback, and PLC I/O mapping.
Where can I buy a genuine 3RT1054-1AV36 with current stock and price?
Sourcing teams need real-time authorized-distributor availability to keep panel build schedules on track.
