Zenith 400A 120-208V 3-Phase Indoor Automatic Transfer Switch



3-Phase 120/208-Volt Light-Duty Switch







The GE/Zenith ZTX400-4I is a 3-phase residential and light-duty automatic transfer switch rated at 120/208 volts. Comes in indoor-mount NEMA 1 enclosure. All Zenith ZTX automatic transfer switches are open transition; this means that the switch does not harbor a built-in circuit breaker for disconnecting utility power before backup power is applied. An electrician who installs the ZTX switch will need to supply an external breaker for safety reasons, however this should be an inexpensive and routine matter. We recommend the 400-amp 3-phase 120/208-volt Zenith ZTX for these Winco standby generators: models PSS21-4, PSS30LS-4, PSS40LS-4, PSS50LS-4, PSS60LS-4, and PSS90LS-4. In addition to NEMA 1 indoor and NEMA 3R outdoor enclosures, this automatic transfer switch available as NEMA 4 indoor/outdoor or NEMA 12 indoor-only models - call T-Rex for details!
