Hubbell Fire Pump Motor Controllers with Automatic Transfer Switches (ATS) are designed to comply with the latest standard of the National Fire Protection Association for the installation and operation of centrifugal Fire Pumps (NFPA-20).Model LXi-2700 is a combined automatic and manual part winding fire pump controller, applied where the capacity of the power source does not permit full voltage starting of the motor. The controller is used with special six (6) lead squirrel cage motors designed for part winding starting. These motors have two parallel stator windings. The motor is started with one winding connected to the line. This winding will develop approximately 65% of its normal inrush current and 42% of its normal starting torque. After a time delay, the second winding is connected to the line in parallel with the first winding. Then the motor will develop its normal running current and rated torque.
