GE Zenith Controls Automatic Transfer Switches (ATS)
✔In today’s increasingly complex power environment, the Automatic Transfer Switch (ATS) is the critical switching device that keeps emergency power systems reliable — automatically transferring the load from the normal source to an alternate source the moment normal power fails. With over 90 years of experience designing and manufacturing automatic transfer switches, GE Zenith Controls serves customers in markets worldwide, delivering not only dependable ATS products but also professional, application-specific power solutions.
🎇1. ZTX Series — Compact Transfer Switching for Small-Capacity Applications
The ZTX series is specifically designed for small-capacity applications where simplicity and reliability matter most.
- Open-transition switching for straightforward, dependable source transfer
- Ideal for end-of-line (branch circuit) transfer and standby power switching
- A perfect choice for standby power applications in light commercial and residential installations
- Available in NEMA 1 or NEMA 3R enclosures to suit both indoor and outdoor installation
🎇2. ZTG Series — Open or Delayed Transition with MX150 Control
The ZTG series lets you choose the transfer mode that fits your load, powered by the advanced MX150 microprocessor control.
- Two transfer modes: ZGS (open transition) for standard break-before-make transfer, and ZGD (delayed transition) with a programmed center-off position that allows rotating motors and transformer fields to fully decay before re-transfer
- MX150 microprocessor control system with an integrated LED/LCD user interface for clear, at-a-glance status indication
- All parameters can be precisely adjusted via the LCD keypad — no special tools required
- Remote communication capability enables convenient remote monitoring of switch status and system performance
🎇3. ZTGSE / ZTGDSE Series — Entry-Level ATS Cabinet Solutions
The ZTGSE/ZTGDSE series packages everything you need in one enclosure — an entry-level, space-saving ATS cabinet solution.
- Includes the ZTG series ATS as the core transfer device
- Integrates the normal-source circuit breaker, surge protective devices and (optional) power quality meters into a single ATS cabinet
- Monitors the emergency power system while effectively safeguarding power quality
- One integrated cabinet means less field wiring, faster installation and a cleaner, more reliable installation
🎇4. ZTS Series — High-Performance Transfer with the MX250 Controller
The ZTS series is engineered for mission-critical and emergency power systems, combining the powerful MX250 controller with three transfer modes to cover virtually every application.
- Three transfer modes: ZSS (open transition), ZSD (delayed transition with center-off time delay) and ZSC (closed transition for make-before-break, virtually interruption-free transfer)
- Exceptional current-withstand capability far exceeds UL requirements
- UL 1008 listed for reliable, code-compliant installation
- For critical loads that cannot tolerate any interruption, bypass-isolation ATS models are available: a quick-make/quick-break manual transfer switch combined with a standard transfer switch allows the ATS to be tested, inspected and serviced without ever de-energizing the load
🎇5. ZTSMV Series — Medium-Voltage Automatic Transfer Switches
The ZTSMV series brings dependable automatic transfer to medium-voltage systems (5–15 kV class).
- Specially designed for medium-voltage power system transfer
- Rated current up to 3,000 A
- Built for business and industrial critical applications that demand reliability and enhanced operation
