Description

SCHNEIDER ACE919CC RS485/RS485 Automatic Transfer Switches

Schneider Electric offers a comprehensive range of Automatic Transfer Switches (ATS), primarily categorized into the high-performance ASCO series and the next-generation modular TransferPacT series. These devices are critical for ensuring power continuity by automatically switching the load from a primary source (Utility) to a backup source (Generator) during power failures.

1. Product Series Overview

• ASCO 7000 Series: The industrial gold standard for mission-critical facilities (Data Centers, Healthcare). Known for high ampacity and bypass-isolation features.

• TransferPacT Series: A modular, “all-in-one” solution for commercial and industrial buildings, designed for easy installation on DIN rails or plates (up to 630A).

• ASCO 300 Series: Ideal for commercial and light industrial applications, providing high-speed transfer and durability.

2. Technical Parameters

While specific parameters depend on the model (e.g., TransferPacT TA16), typical specifications across the range include:

3. Product Advantages

• VisiTrip & VisiSafe (TransferPacT): Provides clear visual indication of device status and ensures safe maintenance downstream.

• High Reliability: Single-solenoid designs in ASCO models reduce moving parts, minimizing potential failure points.

• Modular Upgradability: TransferPacT features “plug-and-play” modules for communication (Modbus, Ethernet) and specialized sensing.

• Cybersecurity: Newer digital controllers are certified to SL1 (IEC 62443) standards to protect against unauthorized remote access.

• Bypass-Isolation: Available on ASCO models to allow maintenance of the ATS without interrupting power to the critical load.

4. Important Considerations (Precautions)

• Transition Selection: Use Delayed Transition for large motor loads to allow residual voltage to decay before switching, preventing mechanical damage or high inrush currents.

• Upstream Protection: Ensure that the circuit breakers or fuses protecting the ATS match the Short-Time Withstand Current ($I_{cw}$) of the switch.

• Manual Operation: Only authorized personnel should perform manual transfers. Ensure the device is in “Manual” mode before using the operating handle to avoid mechanical strain on the motor drive.

• Environmental Protection: For outdoor use, the ATS must be housed in an appropriately rated enclosure (e.g., NEMA 3R or IP54/65).

5. Product Applications

• Mission Critical: Data centers, hospitals, and telecommunication hubs where even a few seconds of downtime is unacceptable.

• Commercial Buildings: Shopping malls, high-rise offices, and hotels for emergency lighting and elevator power.

• Industrial Plants: Protecting continuous manufacturing processes, PLCs, and water treatment facilities.

• Residential/Light Commercial: Small-scale standby systems for retail or luxury homes using the ASCO 185 series.
