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: What can solid state relays be classified according to the trigger form?
Based on trigger form, solid state relay (SSR) can be divided into zero-voltage type (Z) and phase modulation type (P). When the appropriate control signal VIN is applied at the input, the P-type solid state relay turns on immediately. When VIN is undone, solid state relay turns off when the load current drops below the triac's holding current (AC commutation). Z-type solid state relay includes a zero-crossing detection circuit internally. When the input signal VIN is applied, the SSR can be turned on only when the load supply voltage reaches the zero-crossing region, which may cause the maximum delay, half a cycle, of the power supply. Z-type solid state relay has the same turn-off criterion as P-type. But because of its approximate sinusoidal load work current and weak higher harmonic interference, Z-type solid state relay has been widely used.
