TA (FTA976 Assembled with Limited Service Controllers)

Product Information/Sales
Overview

Firetrol® power transfer switches are available completely assembled with Firetrol limited service  fire pump controllers. The entire package of power transfer switch and controller is completely factory assembled, wired, tested and shipped as a complete unit for easy field connection to the power sources and the fire pump motor. The power transfer switch and the electric fire pump controller are assembled in separate but connected enclosure compartments. All wiring between the two enclosures in completed by Firetrol.

The power transfer switches are listed by Underwriters Laboratories, Inc. for transfer switch service and also meet the requirements of NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection and NFPA 70, National Electrical Code. The automatic/manual power transfer switches are listed by Underwriters Laboratories, Inc. under UL-1008, Automatic Transfer Switches, as well as UL-508, Industrial Control Equipment.

Features

The following are included as standard with each transfer switch:

  • Thermal magnetic circuit breaker 
  • 3-pole, double throw transfer switch mechanism, electrically operated, mechanically held
  • ASCO® Group 5 Control module providing for the following:
    -Door mounted operator interface panel with 4 line LED display
    -In-phase monitor
    -Programmable engine exerciser
    -Transfer switch data logging
    -Differential voltage sensing on all phases of the normal power source
    -Voltage sensing of the emergency power source
    -Frequency sensing of the emergency power source
    -Transfer time delay to compensate for momentary power outages of the normal source
    -Retransfer from emergency to normal source is automatically delayed unless the emergency source fails
    -Cool-down timer for unloaded running of the generator set after retransfer to the normal power source
    -Instantaneous retransfer to normal if the emergency source fails and the normal source is available
    -3 second transfer restart delay to reduce current surges when transferring to or from the emergency source
    -NO and NC engine control contacts to start the generator set when the normal power source fails
