  • Detailed Description
    ASCO Transfer Switch Group - Automatic Transfer Switches - Enclosed - Series 7000
    As the world leader in emergency and standby power transfer solutions, ASCO keeps your power on. ASCO, Automatic Transfer Switches and Power Systems safeguard data and telecommunications networks, industrial processes and critical installations from health care facilities to financial transaction centers.

    Over the past 70 years, ASCO has pioneered every major product innovation in power transfer technology. And ASCO is committed to providing a full range of quality-driven products, backed by 24-hour nationwide service support.


    ASCO Series 7000 - ASCO 7000 Series automatic transfer switches when critical power protection is essential.

    Automatic Switch Company (ASCO) provides the solutions to handle the transfer of critical loads to emergency sources reliably and with state of the art products. Using ASCO products can mean the difference between a minor inconvenience and a major catastrophe. You'll find ASCO Automatic Transfer Switches wherever there is a critical load to be protected.

    When flexibility in power switching is a must, ASCO offers a variety of product solutions to meet virtually every application requirement. That's why the 7000 Series is available in the conventional, two-position transfer configuration, plus closed or delayed transition modes of operation. Additionally, switched or overlapping neutral options provide for reliable operation of ground fault protection systems and reduction of voltage transients from unbalanced load switching.

    ASCO automatic transfer switches are the first CE Marked, IEC 60947-6-1 compliant and Kema Keur marked Automatic Transfer switch in the world.

    High speed transfer is total load is accomplished, regardless of ampacity size and is achieved by a reliable, field proven operating mechanism. When combined with a programmable microprocessor controller with keypad and LCD display, this Series offers the most advanced method of transferring all types of loads, such as, motors, electronic drives, UPS's and microprocessor based systems. 7000 Series automatic transfer switches are available Open or Enclosed. Sizes available from 30 through 4000 amps with the largest selection of optional accessories offered anywhere.

    This Series is available in 120 to 600 VAC, UL 1008 listed to 480 VAC for total system loads. True double-throw, inherently interlocked construction to absolutely prohibit connecting both sources together. Contacts easily accessible for easy inspection and preventive maintenance. Meets National Electric Code requirements (U.S.). Rated for critical applications.

    • Standard models in stock, dropped shipped to your location. We will assist you in configuring your switch. Factory engineering assistance is provided at no charge.
    • Available in NEMA Type 1, 3R, 4, 4X, 7and 12 enclosures from 30 to 4000 amps, (some exceptions).
    • Qualified and listed to CSA C22.2 No. 178 and UL 1008 automatic transfer equipment standards.
    • For technical data, dimensions, features, remote controls, monitoring, warranty and other information. See Additional Information below.
