Frequently asked questions
What is the 3RT1075-6SP36-3PA0 used for?
Buyers must confirm it fits heavy-duty motor switching up to 200 kW before quoting or designing it into a panel.
What coil voltage does the 3RT1075-6SP36-3PA0 require?
Control circuit voltage (24 V DC PLC input, 200–277 V AC/DC operating range) determines PLC compatibility and wiring.
Is the 3RT1075-6SP36-3PA0 still in production?
Active vs obsolete status drives whether a buyer specs it for new builds or sources aftermarket/surplus.
What does the -3PA0 suffix mean on Siemens 3RT contactors?
Suffix encodes coil, terminal, and PLC interface options; misreading it leads to wrong part ordered.
What is the difference between 3RT1075-6SP36 and 3RT1075-6SP36-3PA0?
Engineers comparing variants need exact differences to avoid substitution errors on retrofits.
Where can I buy 3RT1075-6SP36-3PA0 with current stock and price?
Sourcing buyers and MRO managers need live distributor pricing and lead time to release purchase orders.
