Product Data Sheet
SSP panel mount relay is part of the Harmony Solid sate relays range. This single-phase panel mount static relay accepts wiring with either bare cable, crimped cable ends, fork lugs or ring lugs. Its rated current is 125A, is controlled with a 4V to 32V DC circuit, has a rated load voltage of 48V to 660V AC output. It also has a test button for easy debugging, testing and commissioning. It mounts on metallic panel surface, with an excellent thermal dissipation capability thanks to its factory-installed thermal pad It has a visual indicator showing the status of its input and a alarm output enabling a quick response to unexpected events. It is a green premium product and conforms to international standard and certifications.
