Its 4-pole design handles three-phase plus neutral switching, common in North American and IEC distribution panels where full isolation is required. Interrupting capacity is the headline here: 220 kA at 240 V AC, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. That SCCR ladder means it can sit upstream of a transformer or in a high-fault industrial service entrance without cascading failure — the breaker clears before the fault energy damages downstream gear. Power loss maxes at 42 W — relevant for enclosed panel thermal calculations, especially when grouping multiple breakers.
Thermal derating and ambient
Above that it derates: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C.
Auxiliary switching and options
The basic switch order code is 3VA12206EF420AA0 if you need to reference the switching mechanism separately.
