LXi-2400 Primary Resistor with ATS

LX-1400 Primary Resistor


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-2400 is a combined automatic and manual reduced voltage primary resistor 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 standard three (3) lead squirrel cage motors. High capacity stainless steel resistors are supplied, which reduce inrush current to approximately 50% of normal. An adjustable timing relay is provided to control the time between reduced voltage start and full voltage run. A manual "emergency run" operator is supplied for emergency starting. When the operator is pushed "on" the motor starts and runs at full voltage until the operator is pushed "off".
