Why Choose the Lovato HS1B6NT090E230 Solid State Relay?
The Lovato HS1B6NT090E230 is a high-current single-phase 90 A solid state relay from the HS1B series, designed for electronic switching of resistive AC loads. Its compact hockey-puck format, SCR semiconductor output and screw terminals make it well suited to industrial heating and automation applications requiring frequent, silent switching without mechanical contact wear.
The HS1B6NT090E230 operates across a wide 24–600 V AC load-voltage range and accepts an equally flexible 18–280 V AC/DC control input. This broad control-voltage capability simplifies integration into industrial control circuits operating at a variety of AC or DC control voltages.
With zero-cross switching, the relay switches its output close to the zero-voltage point of the AC waveform to help reduce switching disturbances. It provides a rated AC-51 resistive-load current of 90 A at 40 °C, together with 4000 V input-to-output isolation, TVS output protection and a high 1200 A non-repetitive surge-current capability at 10 ms.

High-Current Zero-Cross Resistive Load Switching
The HS1B6NT090E230 uses an SCR semiconductor output rather than mechanically operated contacts, enabling frequent and silent switching without the contact wear associated with conventional electromechanical relays. This makes it particularly suitable for high-cycle resistive-load applications such as industrial heaters, heating elements and temperature-controlled process equipment.
Zero-cross operation switches the load near the AC waveform's zero-voltage point, while integrated TVS protection helps protect the output stage against transient overvoltages. Correct thermal management remains essential at high load currents; Lovato specifies a heatsink with thermal resistance of ≤0.3 K/W when operating at the stated rated AC-51 current conditions.
Typical Applications
- Industrial electric heating elements.
- Industrial ovens and furnaces.
- Temperature-control systems.
- High-current resistive load switching.
- Plastic processing and packaging machinery.
- Food-processing and production equipment.
- Industrial automation panels requiring frequent solid-state switching.
