Asco 300

ASCO Series 300 automatic transfer switches are ideal for critical telecom, municipal, commercial, agricultural, and industrial applications up to 3000A. Asco 300's are also designed to handle total system loads including motors and other high inrush and inductive loads.

Available in 1-Phase (2-Pole), 3-Phase (3-Pole with Solid Neutral), and 3-Phase (4-Pole with Switched Neutral) configurations. Service Entrance (SE) Rated models available for each configuration.

Features include:

  • True double-throw operation: The single solenoid design is inherently inter-locked and prevents contacts from stopping between sources or from being in contact with both sources at the same time.
  • Single-solenoid operator derives power to operate from the source to which the load is being transferred, eliminating the possibility of transferring to a dead source.
  • Asco Series 300 Group G Microprocessor Controller with LCD display, keypad, and LED indicators for voltage, frequency, control, timing, and diagnostic functions.
  • Delayed Transition configuration optional on 150-3000A models.

  • Completely front-accessible for installation and operation.
  • Numerous enclosure options including NEMA 1 (indoor) and NEMA 3R (outdoor).
