General Notes

1.The heat generated by the relay needs to be dissipated through the bottom plate, and it is necessary to ensure that the relay 

base plate is in close contact with the heat sink and installed firmly, and the contact surface needs to be covered with thermal pad 

or thermal grease.

2.The relay terminal should ensure that the wiring is firm because the loose wiring will cause the product to heat up abnormally 

and damage the product. The recommended installation torque for M3 terminals is (0.2~0.5)N·m, and for M4 terminals the 

recommended installation torque is (0.98~1.37) N·m.

3.When the ambient temperature is high, please refer to the temperature curve to derate.

4.For the capacitive load, at the moment of turning on, an extremely high inrush current will happen, which may cause SSR to be 

damaged due to excessive inrush current. Therefore, if the load is a capacitive load, or if the load is equipped with a large 

capacitor in parallel, it is strongly recommended to connect the NTC in series in the load circuit to suppress the inrush current to 

avoid damage to the product.
