This interface relay belongs to the Schneider Electric’s Harmony Solid State relays range. This Harmony SSP mount is a 3-phase relay, with zero voltage switching, ideal for resistive loads. It is rated 50A, is controlled with a 4V to 32V DC input and has a rated load voltage of 42V to 660V AC. It is silent, reliable, and has longer operational life thanks to the absence of moving contacts. It has a visual LED indicator showing the status of its input. The interface relay socket connection is by screw connector type. Its dimensions are 104mm (width) x 74.6mm (height) x 41mm (depth) and weighs 0.37 Kg. It comes with IP20 degree of protection. Its design fits industrial machines, packaging, textiles, HVAC, automation control panels, low/medium voltage switchgear, motor controls, PLC Interfaces, power supplies, building or medical equipment, and lighting controls. It is a green premium product that conforms to IEC/EN (62314, 60947-4-2, 60947-4-3), UL 508, C22.2 No 14 standards and certifications like CE, UL, EAC, CSA, UKCA, ROHS and REACH. The SSP3 comes readily equipped with a thermal pad. It is designed for panel mounting by 4 fastener screws. Solid State relays are silent and reliable thanks to the absence of moving contacts which in turn provides longer operational lifecycle.
