Automatic transfer/changeover switching equipment monitors the availability of electrical power and automatically transfers the source, by actuating a genset, for example. ATSE complies with international standard IEC 60947-6-1. The ONCCY EATS2-63 is a PC-class, infrequent change-over ATS featuring a two-position design for switching between Main. Low-voltage automatic transfer switch assemblies provide a reliable means of transferring essential load connections between primary and alternate sources of electrical power. Data centers, hospitals, factories and a wide range of other facility types that require continuous or near-continuous. Multiple utility services may be used as an emergency or standby source of power. Figure 1 shows automatic transfer between two low-voltage utility supplies. Designed for applications where total system coordination must be accomplished, they offer integral overcurrent protection with an electronic trip unit for a variety of standby power.
