The breaker is rated 160 A at 40 °C, 45 °C, and 50 °C without derating, then steps down: 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, and 142 A at 70 °C. For a panel running at 60 °C ambient, the continuous current capability is 151 A — still above the 80 A rating of this specific unit, so no practical derating concern at the nameplate current. Dimensions: 140 mm wide, 158 mm high, 70 mm deep. The 4-pole width is standard for a 160 A frame MCCB — check the existing panel cutout or DIN-rail spacing if retrofitting. The supplied basic switch order code is 3VA12166FF420AA0, which is the base breaker without the UVR; this variant adds the undervoltage release module. ## Power loss and environmental limits Maximum power loss is 35.5 W at rated current. This is dissipated as heat inside the enclosure — factor it into the panel thermal budget, especially in a sealed cabinet with multiple breakers. The storage lower limit is relevant for unheated warehouses in cold climates; the breaker can be stored at -40 °C but must be warmed above -25 °C before energizing. The lifecycle stage is listed as current — meaning Siemens still manufactures this order code as an active catalog item.","metaTitle":"Siemens 3VA1216-6FF42-0CA0 SENTRON MCCB, 80 A, 4-Pole, TM240","metaDescription":"Siemens 3VA1216-6FF42-0CA0 SENTRON molded case circuit breaker, 80 A rated, 4-pole, TM240 release, 220 kA at 240 V.
