This category applies to the switching of electromagnetic loads whose power drawn with the electromagnet closed is more than 72 VA.
Application example: Switching the operating coil of contactors.
This category applies to the switching of electromagnetic loads for which the time taken to reach 95% of the steady state current (T =
0.95) is equal to 6 times the power P drawn by the load (with P
Application example: Switching the operating coil of contactors without economy resistor.
