Category AC1 is applied when using a resistance load which does not necessitate consideration of rush current at starting such as the incandescent light, electric heater, etc.
Application of electromagnetic contactor to Category AC1 is shown in Table3.

Note

*1
The electrical life is 0.5 million times
*2
Category AC1 is not applied to loads such as of mercury lamps where a large rush current flows at starting, and uses where resistance load is controlled at the primary side of the transformer.
*3
Values of (    ) are applied to Enclosure type.
