Frequently asked questions

What is the difference between Class 10 and Class 20 for Siemens motor protection circuit breakers?

The 'Class' designation (e.g., Class 10 or Class 20) refers to the time it takes for the overload relay to trip under a specific overload condition (typically 4.5 times the set current). Class 10 trips faster than Class 20, offering quicker protection for motors that may experience frequent overloads.
