ATC Power Breaker & Power Case Switch Transfer Switch - 1

CAT® ATC POWER BREAKER & POWER CASE SWITCH AUTOMATIC TRANSFER SWITCH Cat transfer switches are designed for a variety of standby power applications. They provide flexibility, reliability and value in a compact package. The open transition power case switch-based Automatic Transfer Switch (ATS) will provide fully functioning transfer in applications where a momentary loss of power is acceptable on retransfer from emergency to normal power supply. The Cat power case switch-based ATS also permits periodic testing of the emergency source without interrupting power to the loads and are available from 200 to 5000 amperes. r Mechanical (cable) and electrical interlocking to prevent paralleling of sources. r Safe manual operation under full load with permanently affixed operating handle r Ambient temperature range: -40°C to 40°C (-40°F to 104°F). r Operating temperature range: -20°C to 70°C (-4°F to 158°F). r Operating humidity: up to 90%. r Relative humidity (non-condensing) r Source paralleling duration is limited to 100 msec or less r Source availability indication r Voltage and frequency sensing r Fastest switching times available (<3 cycles). r Full 60-cycle short time withstand capability r Multiple field programmable time delays r Switch position indication r Source availability indication r Safe manual transfer under load. r Source 1 and 2 auxiliary contacts r Programmable plant exerciser r System test pushbutton r Load shed from emergency r True RMS three phase voltage sensing on Source 1, Source 2 and Load r Frequency sensing on Source 1 and Source 2
