Why Choose the Lovato HS1B5NV060D024 Solid State Relay?
The Lovato HS1B5NV060D024 is a high-performance single-phase 60 A solid state relay from the HS1B series, designed for reliable electronic switching of resistive and inductive AC loads. Its hockey-puck format, semiconductor switching technology and screw terminals make it well suited to industrial heating, motor and machine-control applications where frequent, silent switching is required.
The relay operates with a 24–510 V AC load voltage and is controlled by a 3.5–32 V DC input. Its SCR output uses zero-cross switching, switching the load close to the AC voltage zero point to help reduce electrical disturbances and switching stress compared with uncontrolled switching.
Rated for 60 A AC-51 resistive loads at 40 °C and 12 A AC-53 motor loads at 40 °C, the HS1B5NV060D024 supports both heating and suitable motor-control duties. Input-to-output isolation of 4000 V, integrated VDR output protection and a 1200 V blocking voltage further support dependable operation in industrial control systems.

Reliable Zero-Cross Solid State Switching
Unlike an electromechanical relay, the HS1B5NV060D024 switches its AC load electronically using an SCR semiconductor output and contains no moving switching contacts. This provides silent operation and avoids mechanical contact wear, making solid state relays particularly useful in applications involving frequent switching cycles such as industrial heaters, ovens and automated process equipment.
Zero-cross switching commands the output close to the point where the AC waveform crosses zero voltage, helping limit switching disturbances. When operating at its full AC-51 current rating, appropriate thermal management is essential; Lovato specifies a heatsink thermal resistance of ≤0.55 K/W for operation at the stated rated-current conditions.
