£261.28
The Lovato HS3C6HV020D024 is a robust three-phase solid state relay complete with integrated heatsink, designed for reliable contactless switching of industrial AC loads. As part of the Lovato HS3C solid state relay series, it controls all three phases electronically and combines SCR semiconductor switching with an integrated heatsink for convenient installation in industrial control panels.
This relay uses zero-crossing switching, helping reduce electrical switching disturbance when controlling compatible AC loads. With no mechanical power contacts to wear, the HS3C6HV020D024 provides fast and silent operation and is particularly suitable for applications requiring frequent switching cycles, including industrial heating, process control and automated machinery.
With a rated operating current of 20 A AC-51 at 40 °C, an AC-53 motor-load rating of 12.5 A at 40 °C, a 48–600 V AC rated operating voltage and a 4–32 V DC control input, the HS3C6HV020D024 provides versatile three-phase switching capability. Its integrated heatsink, screw terminals and provision for screw or 35 mm DIN rail mounting simplify installation within industrial control systems.
Solid state relays such as the Lovato HS3C6HV020D024 use semiconductor devices rather than mechanical contacts to control electrical loads. This enables rapid and silent switching without contact bounce or mechanical contact wear, making solid state technology particularly effective for industrial systems involving frequent switching cycles.
The HS3C6HV020D024 electronically controls all three phases and uses SCR outputs with zero-crossing switching. Its integrated heatsink provides the thermal management required by the relay assembly, while high electrical isolation and VDR output protection support dependable operation in industrial heating, motor-control and automation applications.
