The Lovato HS3C6HV025D024 is a three-phase 25 A solid state relay with all three phases controlled, supplied complete with a heatsink for straightforward industrial installation. Part of the Lovato HS3C series, it provides contactless semiconductor switching for compatible resistive and motor loads in industrial automation, heating and machinery applications.
The HS3C6HV025D024 accepts a 4–32 V DC control signal and operates with three-phase loads across a rated voltage range of 48–600 V AC. Its SCR semiconductor outputs use zero-crossing switching, providing quiet operation without mechanical contacts while helping reduce electrical disturbances during compatible AC load switching.
Rated at 25 A AC-51 at 40 °C for resistive loads, 20 A AC-51 at 55 °C and 13.5 A AC-53 at 40 °C for motor loads, this relay is designed for demanding industrial duty. Its integrated heatsink, 5000 V input-to-output isolation, VDR output protection and screw terminals provide a robust, ready-to-use switching solution.
The Lovato HS3C6HV025D024 uses SCR semiconductor outputs on all three controlled phases, providing fully electronic switching without the mechanical contacts used by conventional contactors. This makes it particularly suitable for applications requiring quiet operation and frequent switching cycles.
Its zero-crossing switching, 1200 V blocking voltage, VDR output protection and 5000 V input-to-output isolation provide robust switching characteristics for industrial applications. The supplied heatsink provides integrated thermal management, making the HS3C6HV025D024 a convenient complete assembly for control-panel installation.
