    Note: 
    * 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: SSR relay-ordinary type of Triac output and enhanced type of unidirectional SCR anti-parallel output

    In the case of inductive load, when the solid state relay is turned off by the on-state, a large voltage rise rate dv/dt (commutation dv/dt) will be generated at both ends of the triac due to inconsistent phase of current and voltage. The value exceeding the triac's commutation dv/dt (typically 10V/μs) will lead to delayed turn-off, or even failure. However, the unidirectional triac is unipolar and only affected by satic voltage rising rate dv/dt (typical value 100V/μs). The commutation dv/dt of ordinary type SSR formed by only triac has been greatly improved compared to enhanced SSR composed of two unidirectional SCR in anti-parallel, so the enhanced SSR should be selected in inductive or capacitive load field.

    What capacity the relay would be?
    I want to use a solid state relay to run my motor with 40A rated and 100A inrush current. What capacity the relay would be?

    ATO Responded
    For the motor with 100A inrush current, the solid sate relay current should be 100A or higher, Not 40A.
