- Page 13 Electronic Motor Protection Relays Controls and Settings Trip Cause Indicator Cause of Event Indicator Code Code Displayed Details Overcurrent Under definite time characteristics, trip occurs when current exceeds 112.5 % of set rated (Definite time) current. Under inverse time characteristics, trip occurs when current exceeds set rated current. Overcurrent Reset cannot be carried out when the motor has tripped under thermal inverse time in (Inverse time) order to protect the motor; and reset is possible after a certain span of time has elapsed after the trip. Forcing a reset may cause damage to the motor.

Page 14: Operational Characteristics
Electronic Motor Protection Relays Technical Data Operational Characteristics Contact Characteristics The operational characteristics for the relay’s main contacts (95-96, 97-98) and auxiliary contact (07-08) can be various based on the Cont settings and the Au-c settings. The inverse of normal mode is applied during test mode Menu Setting Contact Output Model... - Page 15 Electronic Motor Protection Relays Contact Output Example for Overcurrent Warning The 07-08 auxiliary contact can be used for overcurrent warning, dedicated ground fault or dedicated instantaneous according to settings. Activating the instantaneous function (Sc) forces the contact to be set for instantaneous. When current flow exceeds overcurrent warning threshold parameters, the warning terminal opens and closes repeatedly every second.
- Page 16 Electronic Motor Protection Relays Technical Data Operational Characteristics Thermal Curve In accordance with IEC 60255-8 Thermal Electrical Relays specifications, protection functions activate based on hot curves and cold curves depending on the thermal characteristics of the load current before an overload can occur. The operating characteristic curves are as shown on the graph, represented as functions of current and time from class 1 to 60.
