Notes:
1 Curve accuracy applies from -20C to +55C. Temperatures above +105C cause an
overtemperature protection trip.
2 There is a memory effect that can act to shorten the long delay. Approximately ve
minutes is required between overloads to completely reset this thermal memory.
3 Total clearing times shown include the response times of the trip unit, the breaker
opening, and the interruption of the current.

5 For high fault current levels an additional xed instantaneous hardware override is
provided at 2500A ±10%.
