The 160 A rating holds flat from 40 °C to 50 °C; above that it derates 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 — so in a warm cabinet you lose about 10 % at the top end. The interrupting ratings climb steeply as voltage drops: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. This is a line-protection version (not a motor-protection or generator breaker), so it is sized for feeder and distribution circuits in switchboards, panelboards, and downstream sub-distribution. What you get is a rugged, no-frills MCCB for standard overcurrent and short-circuit protection on cable and bus.
Auxiliaries and release options
That gives you two N.O./N.C. pairs for status feedback plus a dedicated alarm contact that changes state only on a trip event. The integrated auxiliary trip (the UVR coil) has its own order code 3VA9608-0BB24 if you ever need a replacement. No ground-fault monitoring module is included, and there is no voltage-trip (shunt-trip) release on this build.
The 76.2 mm width is a standard 3-pole MCCB footprint — three 25.4 mm pole centers — so it fits existing SENTRON 3VA panel cutouts and busbar systems without modification.
