4 Technical Information Series imetallic Overload Relays Tripping Characteristics Trip Class 10A These tripping characteristics comply with IEC 947 and are the mean values of the scatter bands at 20 C ambient temperature starting from the cold state. Tripping time is a function of operating current. In equipment at operating temperature, the tripping time of the overload relay falls to approximately 1/4 of the read value.
