Three Phase Automatic Transfer Switch
The ASCO 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 series 230 is available in 5 different frame sizes up to 800A and can operate in multiple control modes including automatic, remote and manual operation.
The Series 230 transfer switch is available in single and three phase configurations up to 80A, and for higher power applications in three phase configurations up to 800A, up to 415 volts and for both 50 and 60 Hz.
