This Harmony SSP solid state panel mount single-phase relay is rated 125A, is controlled with a 90V to 280V AC input, has a rated load voltage of 48V to 660V AC with zero voltage switching, ideal for resistive loads. It has a visual indicator showing the status of its input and a alarm output enabling a quick response to unexpected events. It also has a test button for easy debugging, testing and commissioning. It is also silent and reliable thanks to the absence of moving contacts.
