What the 160 A rating and interrupting capacity mean for your panel
The 3VA2116-6HN32-0BA0 is a SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous current at 40 °C, with no derating needed up to 50 °C — above that it steps down to 154 A at 55 °C and 136 A at 70 °C, so the thermal curve matters if your enclosure runs hot. The interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 5 kA at 690 V, which covers most industrial fault-current scenarios up to the low-voltage switchgear boundary.
Integration and mounting constraints
No auxiliary contacts are integrated, and the undervoltage release (UVR) is built in, so if your safety circuit expects a shunt trip instead, you'll need a different variant or an add-on module. The base switch is order code 3VA2116-6HN32-0AA0; the integrated auxiliary trip is 3VA9608-0BB11.
Operating environment and electrical ratings
Latching endurance rated at 20,000 operations.
