Note 1 Selective trip coordination is not available.
Note 2 Selective trip coordination is available. (Instantaneous trip current must be adjusted
for coordination.)
Note 3 Selective trip coordination is available. Make sure however that the short-circuit
current where the MCCB is installed is less than its breaking capacity.
Note 4 Selective trip coordination is available.
