Replacement & Compatibility FAQ
Q: Can the ATS48C21Q replace an ATS22 series soft starter?
A: Not directly. The ATS22 and ATS48 use different mounting footprints and control wiring. A wiring adaptation is required. Contact us for a migration guide.
Q: Is the ATS48C21Q compatible with 690 V systems?
A: Yes. It supports supply voltages from 208 V to 690 V AC, making it suitable for both 400 V and 690 V motor systems.
Q: What is the difference between ATS48C21Q and ATS48C21Y?
A: The suffix Q denotes 380–415 V optimized rating; Y denotes 200–240 V. Verify your supply voltage before ordering.
Q: Can I use the ABB PSE210 as a drop-in replacement?
A: Functionally equivalent in most cases, but terminal layout and parameter configuration differ. Panel modifications may be needed.
