WebWhat is the trip Class of overload relay? The time taken by them to open the contactor during overloads is specified by the trip class. It is commonly classified into Class 10, Class 20, Class 30, and Class 5. The OLR trips in 10 seconds, 20 seconds, 30 seconds, and 5 seconds respectively at 600% of full load current to the motor. WebThis function is plotted on the inverse time curve below, and is termed as the trip class. The trip class also indicates the time taken by the relay to open in an overload condition. Trip Classes 5, 10, 20, and 30 are common. These classes suggest that the overload relay will trip in 5, 10, 20, and 30 seconds.
