Example 1: A heater with a rated current of 15A, and the heater is a resistive load, then the formula: 15A×2=30A, you must choose to buy a 40A solid state relay. Example 2: A motor with a rated current of 15A, and the motor is an inductive load, then the formula: 15A×6=90A, you must choose to buy a 100A solid state relay.
