Solenoid Valve Application Characteristics: When activated, solenoid valves may experience several times the surge current, and upon deactivation, there may be a reverse electromotive force. However, the power of solenoid valves used in household appliances typically ranges from a few watts to several tens of watts. Therefore, a 5A relay is commonly chosen.

Typical Loads: Air conditioning four-way valves, washing machines, drain valves, etc.

Lighting Fixture Application Characteristics: Lighting loads typically experience significant surge currents upon activation, requiring specific confirmation before selection.

Typical Loads: Refrigerator lights, microwave oven lights, UV lights in sterilizers, etc.
