E300 Series
Single Sided Bypass/Isolation
Commercial and Industrial Applications
Automatic Transfer Switch 100-1200A - 200-600V
The E300 Series of transfer switches are built for general purpose commercial and industrial applications requiring the dependability and ease of operation found in a power contactor switch. The E300 Series is built using ABB ZTG Series automatic transfer switch; the ZTG ATS is built for standard applications requiring the dependability and ease of operation found in a power contactor switch.
Design and Features
- Single sided bypass isolation on emergency
- Close differential 3 phase under-voltage sensing of Source 1 (normal)-factory standard setting 90% pickup, 80% dropout (adjustable); under-frequency sensing of Source 1 factory setting 95% pickup (adjustable)
- Voltage and frequency sensing of the Source 2 (emergency) factory standard setting 90% pickup voltage, 95% pickup frequency (adjustable)
- Test switch (fast test/load/no load) to simulate Source 1 (normal) failure automatically bypassed should the Source 2 (emergency) fail
- Centralized Termination Point for ease of installation
- NEMA Type 1 enclosure is standard also available in NEMA 3R
- Ratings 100 to 1200 amps (3 poles or 4 poles up to 600A)
- Double throw, mechanically interlocked contactor mechanism
- Electrically operated, mechanically held
- Designed for emergency and standby applications
- Higher kA rating option (up to 65)
