The 187 kA breaking capacity at 240 V and 121 kA at 415 V tell you it can interrupt high-fault currents without cascading upstream — critical for a motor branch circuit where the supply transformer can deliver a stiff short. Breaking capacity drops with system voltage: 187 kA at 240 V, 121 kA at 415 V, 30 kA at 440 V, and 17 kA at 690 V. That 30 kA at 440 V is the figure to check if your panel feeds a 440 V motor starter — the part still clears faults comfortably for most industrial installations. On the thermal side, the 160 A rating holds up to 50 °C ambient; above that it derates stepwise to 144 A at 70 °C. If the MCCB sits in a hot enclosure near drives or transformers, use the 60 °C column (150.4 A) for your continuous load calculation. Dimensions are 105 mm wide × 158 mm high × 70 mm deep — fits standard 3-pole MCCB mounting footprint on a DIN rail or panel-mount base. The IP40 front protection means the operator interface is dust-protected but not sealed against hose-down; install in a clean, dry enclosure or behind a gland plate.","metaTitle":"Siemens 3VA1216-5MH32-0AC0 SENTRON MCCB, 160 A, 187 kA at 24","metaDescription":"Siemens 3VA1216-5MH32-0AC0 SENTRON molded case circuit breaker, 160 A rated continuous current, 3-pole, TM120M thermal-magnetic release, 187 kA at 240 V.
