When the load current is higher than 10A, a heat sink must be installed to the solid state relay, or the SSR relay should be mounted on a metal base plate with heat dissipation effect, and the thermal grease is applied between them.
When the load current is 40A or more, a fan cooling radiator or water cooling radiator must be equipped.

Tips: The ambient temperature for solid state relay
Load capacity of SSRs is greatly affected by the ambient temperature and its own temperature rise. During installation and use, good heat dissipation should be ensured. The product with the rated working current above 10A should be equipped with a radiator and above 100A should be a radiator and a fan for forced cooling. In the installation, pay attention to good contact between the bottom of the relay and the radiator, and consider appropriate amount of thermal grease coated in order to achieve the best cooling effect.
If the relay is working at high temperature (40 ℃ ~ 80 ℃) for a long time, the user can consider derating to ensure normal operation according to the maximum output current and ambient temperature curve data provided by the manufacturer.
