Why is it important to include electrical ratings for magnetic contacts?

Including electrical ratings for magnetic contacts is essential because it informs electrical workers about the contact's limitations. These ratings specify the maximum voltage and current that the contacts can safely handle. Without this information, there is a risk of overloading the contacts, which could lead to malfunctions or failures that might not only damage the equipment but could also pose safety hazards during installation or maintenance. This aspect is critical for ensuring safe and reliable operation in any system that integrates magnetic contacts, as workers need to know what the contacts are rated for to avoid exceeding their operational limits.

The other aspects of the options, while relevant to the proper functioning of magnetic contacts, do not address the fundamental importance of safety and compliance with electrical standards that come from clearly defined electrical ratings.
