MCCB for motor branch circuits
Designed specifically for motor protection, it includes phase failure detection and a configurable short-time delay adjustable between 4 s and 15 s, letting you coordinate with downstream starters and avoid nuisance trips on inrush.
SCCR and selectivity
Interrupting capacity is 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 5.2 kA at 690 V. The adjustable short-time delay (4–15 s) supports zone-selective interlocking — downstream faults clear fast; upstream holds coordination.
Integration and auxiliary contacts
No ground-fault monitoring or undervoltage release on this variant — if those are required, the 3VA2220-5MN32-0AA0 basic switch is the base platform.
