This ASCO Series 300 SE Non-Automatic Transfer Switch is electrically operated and manually initiated for single phase loads up to 70A. Service Entrance rated. Designed for commercial, telecom, municipal, light industrial, and agricultural applications.

TRANSFER SWITCH FEATURES

  • Ideal for applications where operating personnel are available and the load is not an emergency type requiring automatic transfer of power.
  • Transfer is manually initiated via soft key on the user interface panel.
  • Controller prevents inadvertent operation under low voltage condition.
  • Source acceptability lights inform operator if sources are available to accept load.
  • Source in-phase monitor to transfer motor loads between live sources.
  • Two auxiliary contacts closed when transfer switch is connected to normal and two closed on emergency standard feature 14AA/14BA.
  • 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.
  • Operating parameters and feature settings can be adjusted without opening enclosure door.
  • Supplied with solid neutral termination.
  • Compact design for optimum utilization of space.
  • Designed to be completely front- accessible, permitting the enclosure to be installed flush to the wall and still allow installation of all power cables and connections from the front of the switch.
  • Numerous enclosure options including UL Type 1 (indoor) and UL Type 3R (outdoor).
  • Accessory 44A Strip Heater is now included for all models with a 3R outdoor enclosure. Prevents condensation and freezing that can shorten the life of the ATS. External 120 volt power source required. Thermostat included.
  • Accessory 11BE Feature Bundle is now included with all new Asco 300 ATS. This accessory offers an event log, enabled RS-485 communication port, and common alarm output contact.
  • UL 1008 Listed and CSA Certified.

SERVICE ENTRANCE FEATURES

  • Suitable for use as service entrance equipment. Listed to UL 1008 (standard for panel-boards) and meets all NEC requirements for service entrance use.
