Its 3-pole construction and 242 kA breaking capacity at 240 V (187 kA at 415 V, 121 kA at 500 V, 7.5 kA at 690 V) mean it can interrupt fault currents up to those levels without upstream cascading, making it suitable for high-fault service-entrance or distribution positions where SCCR headroom is critical. The trip indicator confirms the breaker has opened on fault, a useful diagnostic for remote monitoring or panel walk-downs.
Integration notes
Mounts in a standard panel or enclosure — it is a DIN-rail-mountable MCCB (the SENTRON 3VA series uses a snap-on foot for 35 mm DIN rail). The undervoltage release (UVR) requires a separate control voltage; verify the coil rating matches the panel's control supply before wiring. Maximum power loss is 40 W at full rated current. That is modest for a 250 A frame, but in a densely packed panel with multiple breakers, the cumulative heat should be factored into the enclosure ventilation calculation.
