Series 230 Automatic Transfer Switch
The Recognized Leader in Power Transfer
Switch Technology Offers the Most
Advanced Transfer Switches in the World.
Product Overview
The Series 230 automatic transfer switch consists of an
intelligent controller and a modular load break switch which
automatically transfers the load to the emergency power
source when it detects the normal power source under/over
voltage, under/over frequency, or phase loss. The switch has
three operational positions (Source I, Center-off, Source II).
The two sources are isolated when the switch is in the centeroff position. A center-off position locking mechanism is also
provided.
Application
The Series 230 transfer switch is rated up to 800A and is available from 220 to 415 volts for both 50 and 60 Hz, single and three
phase. Typical applications include commercial and residential buildings, hospitals, telecom, subway and transportation, data
centers, military and fire pumps.

C2000 Controller with energy storage
The optional controller with energy storage (Accessory 1H) has an added feature to switch the
transfer switch to the center-off position during Source I and Source II failure at the same time. The
controller will remain in center-off until either Source I or Source II power is restored and voltage and
frequency are both stable. This optional feature can work in Source I Priority and No Source Priority
operating modes. This feature is available only after the controller has been powered by AC input
for at least10 minutes to charge a capacitor. This Accessory can only be installed in the factory. Use
accessory code 1H when ordering this function.
