At 55 °C it still handles 76.8 A; at 70 °C it's good for 72 A — useful if the panel runs hot or shares space with drives. Breaking capacity is rated across four voltage levels: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. That covers most industrial distribution panels up to 690 V line-to-line. This is the line protection version — it's built to protect feeders and branch circuits, not motor overloads. If you need motor protection, you'd pair it with a separate overload relay. The 3-pole form factor fits standard MCCB mounting; the 70 mm depth, 76.2 mm width, and 130 mm height keep the footprint compact for multi-breaker panels. ## Undervoltage release included — no auxiliary contacts There is no separate auxiliary contact block; if you need status feedback for a PLC, you'll add one externally.","metaTitle":"Siemens 3VA1180-3EF36-0DA0 SENTRON MCCB, 80 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1180-3EF36-0DA0 molded case circuit breaker, 80 A rated continuous current, 3-pole, TM240 release, 75.6 kA at 240 V.
