Selection Notes
Choose the Inst (instantaneous) version over a selective release when the circuit has no downstream residual current devices to coordinate with and the priority is the fastest possible earth-fault trip. The 85-690 V AC operating range covers both 400 V and 690 V distribution without needing a separate release for each voltage class.
