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 under/over voltage, under/over frequency, or phase failure. The switch has three operation positions (source one - center off - source two). The two sources can be isolated in the center off position. A position locking mechanism is also provided.
Application
The Series 230 capacity is up to 400A, available from 220 to 415 volts, 50 and 60Hz, single phase and three phase. Typical applications include office buildings, residential buildings, telecom, hospital, subway, data center, military, transportation, and fire pump applications.
