The Zenith ZB30 is a UL tested 30-cycle short time rated Bypass/Isolation Transfer Switch that is utilized with Over Current Protective Devices (OCPD) to facilitate selective coordination. The ZB30s industry leading short time rating and best-in-class footprint greatly simplifies the selective coordination design process and provides the utmost in system design flexibility for future system growth. The ZB30 supplies 100% rated power to loads after an overcurrent event, helping to maximizing power distribution system reliability and uptime. The ZB30 is available in standard, delayed and closed transition modes.
The ZB30 Series Bypass-Isolation Transfer Switches are the solution when interruption of power during service or testing is not acceptable. Consisting of two major modules-the Automatic Transfer (ATS) and the Bypass/Isolation Switch – the ZB30 Series incorporates the rugged construction of all our ZT30 Series automatic switches with a quick make/quick break bypass switch manual load transfer handle (for standard and delayed transition only) and our control/interlock system, which consists of both mechanical and electrical interlocks.
The bypass uses normal failure sensing and a time delay to start the engine automatically if a failure occurs when the ATS has been removed for service, which can be done without disturbing the load.
