Product Data Sheet
This Harmony SSP solid state panel mount 3-phase relay is rated 50A, is controlled with a 18V to 36V AC input, has a rated load voltage of 48V to 530V AC with random voltage switching, ideal for inductive 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. 0 0 0 0 0 0 0 0 0 0 0 0
