Rating and fit
The interrupting capacity is the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. Thermal derating is published across the operating range: the breaker holds 160 A continuously up to 50 °C, then tapers to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C.
The 76.2 mm width is a standard 3-pole MCCB footprint — it fits the same DIN-rail or mounting-plate cutout as other 160 A frame breakers, so a panel laid out for a 3VA1112-5EF32-0CA0 will accept this unit without drilling new holes or moving the bus bars. That gives one NO/NC for status feedback and one dedicated alarm contact that changes state only on a trip event — useful for remote fault annunciation without adding an external relay.
