  • 1.product overview

    The YUYE YES1-250GA/4P 250A PC-Class Automatic Transfer Switch (ATS) is designed for automatic power source transfer between two power supplies, such as utility mains and a backup generator. Rated at 250A (4-pole, 3-phase + neutral) for 400V AC systems, it is suitable for three-phase, four-wire power distribution systems where neutral switching is required. Its PC-class switching design supports reliable source changeover, while the mechanical interlocking mechanism helps prevent both power sources from being connected simultaneously.

    The  YUYE YES1-250GA/4P 250A PC-Class Automatic Transfer Switch (ATS) conforms to IEC60947-6-1 standard, and obtains CCC,CE, TUV certificates.

    5. Frequently Asked Questions

    Q1: What is the main function of YES1‑250GA ATS?

    A: It automatically switches load between utility mains and backup generator to guarantee continuous power supply for critical loads.

    Q2: What system does this 250A ATS apply to?

    A: Rated AC400V, suitable for 3‑phase 4‑wire distribution systems; available in 3P /4P versionsABB Group.

    Q3: What does PC‑class ATS mean?

    A: PC‑class is integral switch‑body design with reliable mechanical interlock, preventing simultaneous closing of two power sources. It focuses on source transfer; short‑circuit protection shall be realized by upstream protective devices.

    Q4: What certifications and standards does this product comply with?

    A: Complies with IEC 60947‑6‑1 standard, with CCC, CE, CB certificates.

    Q5: Does YES1‑250GA support fire‑fighting function?

    A: Yes, it is equipped with fire‑fighting signal input function for fire‑linked cut‑off requirement.

    Q6: What control voltages are supported?

    A: Support DC12V, AC110V, AC220V control power supply.

    Q7: Can manual operation be performed?

    A: Yes. It features 3‑position (0‑I‑II) local manual operation. Do NOT manually switch under live‑load condition.

    Q8: Can it work with diesel generator sets?

    A: Yes. It monitors source status and transfers load after generator stabilizes. It cannot directly control generator start‑stop signal.

    Q9: What frame current options are available for YES1 series?

    A: Frame ratings:100A,250A,630A,1600A,3200A; rated current range:16A‑3200A.
