Autotraansformer Starting
Firetrol® FTA1800 Autotransformer Starting Fire Pump Controllers use an autotransformer to supply reduced voltage when starting the motor. The controller is of the closed circuit type where the motor circuit remains closed during the transition from start to run resulting in minimum line disturbance. The controller monitors, displays and records fire pump system information. The autotransformer has three taps for selection of starting current and torque; 50% tap for 150% current and 25% torque, 65% tap (factory setting) for 250% current and 42% torque and the 80% tap for 384% current and 64% torque.

Firetrol fire pump controllers are listed by Underwriters' Laboratories, Inc., in accordance with UL218, Standard for Fire Pump Controllers, CSA, Standard for Industrial Control Equipment, and approved by Factory Mutual. They are built to meet or exceed the requirements of the approving authorities as well as NEMA and the latest editions of NFPA 20, Installation of Centrifugal Fire Pumps, and NFPA 70, National Electrical Code.
