Motor protection curve
NettetMotor Protection Fundamentals - IEEE Web Hosting NettetTrip classes according to NEMA. NEMA Standard MG-1 defines 4 types of Classes. The most common classes are 5, 10, 20 & 30. Class 5, 10, 20 & 30 overload relays will trip within 5, 10, 20 & 30 seconds respectively at 600% of motor full load amps. A Class 10 overload relay, for example, has to trip the motor offline in 10 seconds or less at 600% ...
