This series of automatic transfer switches is designed for residential and light commercial critical/non-life safety applications requiring dependability and ease of operation. These switches combine reliability and flexibility in a small, economical package. ZTX switches work together with any remote-start generator that use two-wire control, allowing the standby power system to be fully automatic.

The transfer switch monitors utility and generator power. When utility power fails or is unsatisfactory, the control starts the generator set and transfers the load to the generator set as soon as the generator reaches speed and voltage. When utility power is restored the transfer switch automatically transfers back to utility power, shutting down the generator and instantly resetting itself for the next power interruption. No action is required by the owner.

We recommend ZTX switches when purchasing any packaged standby generator systems. If you require optional features such as auxiliary contacts, extra power poles to switch neutral, special enclosures or communications features, we recommend that you purchase a Zenith industrial class of switch.
