Lovato HS1B6NT060E230 is a single-phase 60 A solid state relay with an 18–280 V AC/DC control input, 24–600 V AC rated operating voltage, SCR output and zero-crossing switching for industrial resistive loads.

The Lovato HS1B6NT060E230 is a high-capacity single-phase 60 A solid state relay designed for reliable electronic switching of AC resistive loads. Part of the Lovato HS1B series, its compact hockey-puck construction uses an SCR semiconductor output to provide silent, contactless switching for demanding industrial automation and heating applications.
The HS1B6NT060E230 accepts a wide 18–280 V AC/DC control voltage and switches loads across a rated operating voltage range of 24–600 V AC. Its zero-crossing switching activates the output close to the AC waveform's zero-voltage point, helping reduce switching disturbances when controlling compatible resistive loads.
Rated for 60 A AC-51 at 40 °C and 52 A AC-51 at 55 °C, this relay is suitable for substantial heating and resistive-load applications when correctly installed and cooled. High electrical isolation, integrated TVS output protection and robust screw terminals make it a dependable choice for industrial machinery and control panels.
The Lovato HS1B6NT060E230 switches AC loads electronically through an SCR semiconductor output, eliminating the moving contacts found in conventional electromechanical relays. This contactless design provides quiet operation and is particularly valuable in applications requiring frequent switching of industrial resistive loads.
Its zero-crossing switching and high 1200 V blocking voltage provide robust switching performance for compatible AC loads. Thermal management is essential at high currents, and Lovato specifies a heatsink thermal resistance of ≤0.55 K/W for operation at the stated AC-51 rated currents and temperatures.
