What is the main difference between power rated contacts and pilot rated contacts?

The main difference between power rated contacts and pilot rated contacts lies in their current handling capabilities. Power rated contacts are designed to handle higher current levels, making them suitable for applications where significant electrical loads are involved. This capability allows them to reliably control heavy-duty electrical devices and systems, such as motors and large appliances, without overheating or failing.

In contrast, pilot rated contacts are typically used for lower current applications, particularly in control circuits and signaling. They can efficiently manage the control of larger power devices but do not handle the high power levels directly. By utilizing power rated contacts in appropriate applications, one can ensure safe and effective control of high-current electrical systems. This distinction underscores the importance of selecting the right type of contact based on the specific electrical requirements of the system being designed or maintained.
