At 415 V and 440 V it still delivers 187 kA, and at 500 V it's 121 kA; the 3 kA at 690 V is the tail end of the curve for odd-voltage industrial loads.
The 86 mm depth clears most standard enclosure back-pan depths. The 140 mm width for a 4-pole MCCB is a standard SENTRON frame size, so busbar kits and mounting feet fit without modification.
Selectivity and coordination
With a minimum trip setting of 60 A and a full-scale value of 40 A, this breaker is set up for a 40 A feeder. The ground-fault monitoring uses summation current formation on L + N conductor.
Communication and auxiliary functions
This MCCB includes a communication function, so it can integrate with a monitoring system for remote trip indication or load data. The 2.2 W maximum power loss is low enough that multiple breakers in a panel don't create a thermal problem — useful when you're stacking feeders in a compact enclosure.
