Asco 300-230A-3Ph-Open Transition ATS-NEMA 1



ůSpecify the Voltage You Need When Placing Order







Asco's commercial-grade 300-Series 3-phase automatic transfer switches are available from T-Rex in three voltages: 120/208, 120/240, and 277/480. Be sure to select the proper voltage for your application during checkout. Prices do not change based on voltage choice. The Asco 300 switches we offer are open transition; an open-transition switch does not contain its own built-in circuit breaker to disconnect utility power before backup power is employed. For safety reasons, the electrician handling installation of the switch must supply an external breaker, however this should be a routine, inexpensive procedure. We recommend this 230-amp automatic transfer switch for the following Winco standby generators: models PSS21-4, PSS21-17, PSS21-18, PSS30LS-4, PSS30LS-17, PSS30LS-18, PSS40LS-4, PSS40LS-17, PSS40LS-18, PSS50LS-4, PSS50LS-17, PSS50LS-18, PSS60LS-4, PSS60LS-17, PSS60LS-18, PSS90LS-4, PSS90LS-17, and PSS90LS-18.
