Lovato HS1B6NT060E230 60 A Solid State Relay, 18-280 V Control

A 60 A hockey-puck solid state relay for AC loads

The HS1B6NT060E230 is a single-phase solid state relay in the hockey-puck format from the Lovato Electric HS1 series. It switches AC loads up to 60 A at 40 degC (derating to 52 A at 55 degC) at an operating voltage of 24-600 VAC, with a thyristor (SCR) output and zero-crossing switching.

The control input accepts 18-280VAC/DC, with pick-up at 18 V and drop-out at 8 V. The blocking voltage is 1200 V, non-repetitive surge current 750 A, on-state drop 1.45 V, and input-to-output isolation 4000 V.

Technical specifications

Selecting the relay

A solid state relay needs a heatsink: the datasheet specifies a heatsink thermal resistance of ≤0.55 K/W for full rated current at 40 and 55 degC, and the junction-to-case resistance is 0.4 K/W. Without sufficient cooling the usable current drops.

In the catalogue the E230 suffix corresponds to the 18-280 V AC/DC control input and the D024 variants to a DC-only control input. Choose the version that matches your controller output (a PLC output at 24 V DC, or a 230 V AC thermostat).

Applications and mounting

Typical duty is switching resistive heaters in plastic processing, packaging and furnace control, where mechanical contactors would wear out under frequent switching. Match the load type: inductive loads and motors need derating or special SSR versions.

Mount the relay on a flat, clean heatsink with thermal compound, tighten the screw terminals to the torque in the datasheet, and protect the circuit with ultra-fast fuses where the datasheet requires.

For panel design and commissioning, the practical figures to keep at hand are: operating voltage drop-out 8 V; off state leakage current 1 mA; on state output voltage drop 1.45 V; critical rate of rise of off-state voltage dv/dt 500 V/µs; non repetitive surge peak on state current t=10ms 750 A; I2t 2800 A2s; input – Output isolation 4000 V; input – Output to metal base 4000 V; control terminals Screw M4 Type; terminals tool PZ2; operating temperature (min) -55 °C; operating temperature (max) +90 °C; storage temperature (min) -55 °C; storage temperature (max) +125 °C. These come straight from the datasheet and are repeated here so that the key installation limits are visible without opening the PDF.
