LXi-2300 Autotransformer with ATS

LX-2300 Autotransformer

Description

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-2300 is a combined automatic and manual reduced voltage autotransformer 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. A heavy-duty autotransformer is supplied with standard taps at 50%, 65% and 80% to reduce the starting voltage to the motor. The autotransformer is factory wired to the 65% taps unless otherwise specified when ordered.

The starting inrush current drawn from the power source is reduced to approximately 25% of normal when using the 50% tap, 42% of normal on the 65% tap, and 64% of normal on the 80% tap.

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".
