Schneider VIP400 Relay - interlocking between successive stages of overcurrent and earthfault prot

Schneider VIP400 Relay - interlocking between successive stages of overcurrent and earthfault prot

(OP)
Does the Schneider VIP400 and VIP410 relay have settings which enable interlocking between successive stages of overcurrent and earth fault protection ?
In the attached file, the blue curve has no interlocking.
The red curve is interlocked such that the second stage ( I>> ) prevails if it is faster than the blue curve.

No idea about that relay in specific, but generally all of the tripping conditions are ORed together so that the fastest one produces the trip. Logic allows other combinations and permutations.
