Why Choose the Original ATS48C25Q
- Proven reliability — Altistart 48 series has millions of installations globally across heavy industry.
- Built-in bypass contactor — eliminates need for external bypass, reducing panel space and wiring complexity.
- Advanced motor protection — thermal overload, phase loss, phase imbalance, and locked rotor protection built in.
- Torque control algorithm — ensures smooth, jerk-free starts even under variable load conditions.
- Wide voltage range — 208–690V covers global applications without hardware changes.
- Seamless Schneider ecosystem integration — compatible with Modbus, CANopen, DeviceNet, and Profibus via optional cards.
Typical Applications
- Pumps and compressors (water treatment, HVAC, oil & gas)
- Conveyors and belt drives (mining, logistics, food processing)
- Fans and blowers (industrial ventilation, power generation)
- Crushers and mixers (cement, chemical, aggregate)
- Centrifuges and agitators (pharmaceutical, wastewater)
System Compatibility
- PLC Integration: Compatible with Schneider Modicon M340, M580, Premium, and Quantum PLCs via Modbus RTU/TCP.
- SCADA/DCS: Integrates with EcoStruxure, Vijeo Citect, and third-party SCADA via standard protocols.
- Motor Types: Squirrel-cage induction motors (standard and high-efficiency IE2/IE3).
- Bypass: Internal bypass contactor rated for continuous duty — no external contactor required.
Selection Guide
Use the following criteria to confirm the ATS48C25Q is the correct model for your application:
- Motor FLA ≤ 250A — soft starter current rating must meet or exceed motor full-load amps.
- Supply voltage 208–690VAC, 3-phase — confirm site voltage matches.
- Starting duty cycle — standard duty (10 starts/hour); for heavy duty, consider ATS480 series.
- Bypass required? — built-in bypass is standard; no external contactor needed.
- Communication needed? — order optional VW3A48101 (Modbus) or VW3A48121 (Profibus) card separately.
- Enclosure rating — ATS48C25Q is IP20; for IP65 install in appropriate enclosure or select ATS48 enclosed version.

Replacement & Compatibility FAQ
Q: Can the ATS480C25Q directly replace the ATS48C25Q?
A: Yes. The ATS480 series is the next-generation successor with enhanced diagnostics and energy monitoring. Control wiring is largely compatible but verify parameter settings before commissioning.
Q: Is the ATS48C25Q compatible with IE3 high-efficiency motors?
A: Yes. The torque control algorithm is compatible with IE2 and IE3 motors. Adjust motor parameters (FLA, thermal class) in the starter settings.
Q: Can I use the ATS48C25Q without a bypass contactor?
A: The ATS48C25Q includes an internal bypass contactor — no external bypass is required for standard applications.
Q: What is the difference between ATS48C25Q and ATS48C21Q?
A: The C25Q is rated 250A / 132kW; the C21Q is rated 210A / 110kW. Choose based on your motor’s full-load current.
Q: Do you supply original Schneider Electric units?
A: Yes. All units are sourced from authorized channels. Certificates and traceability documentation available on request.
