Single Phase Solid State Relay - 40A

Single Phase Solid State Relay - 40A

Item is in stock


This single phase solid state relay is ideal for switching high current devices, such as a heating element.

It has a plastic cover to protect against contact with live terminals and a LED that illuminates when the load is being switched.


  • Load Current: 40A
  • Load Voltage: 380VAC
  • Input Voltage: 3-32VDC
  • Dimensions (LxWxH): 57.3 x 44.8 x 31.7mm
  • Full Specifications: Click Here

It is recommended to use the relay in conjunction with a heat sink if switching more than 2A. The relay has a metal base for good thermal contact with a heat sink.

Note: If using the relay to switch a very low current device such as a CFL or LED light bulb, the bulb may appear to "blink" when the relay is off. This is due to the <2mA leakage current slowly charging the capacitor in the bulb. When the capacitor has enough charge the bulb will illuminate, then switch off and the cycle will repeat. This can be resolved by placing a resistor across the load terminals.
