Firetrol FTA1350 Wye-Delta

Description

Firetrol FTA1350 Wye-Delta, Closed Transition Starting Fire Pump Controllers are used with delta-wound squirrel cage motors. FTA1350 controllers are of the closed circuit transition type in which the motor circuit remains closed during the transition from start to run. The controller monitors, displays and records fire pump system information.Actuating the controller via pressure, START push-button or deluge valve contact closes the start contactor connecting the motor to the line in the wye connection. The motor will draw approximately 33% of its normal inrush current and develop approximately 33% of its normal starting torque. After a time delay, the motor is automatically reconnected in delta, applying full voltage to the motor windings. During this transition, a resistor is connected to each phase, minimizing line disturbances and voltage drop during starting. These controllers are recommended especially for use with generator sets.

Brand

Firetrol

Firetrol, was founded in the early 1970’s and incorporated in Erie, Pennsylvania by an entrepreneur who saw an opportunity in a unique marketplace; the fire pump control industry. The business grew steadily between 1971 and 1980 as the company developed the first fire pump controller with molded case circuit breakers which drastically reduced their size, the first manual wound rotor controller for the New York City high-rise marketplace, the first medium voltage controller, and the first UL Listed controller with an automatic power transfer switch.
