The 80 A rating holds flat from 40 °C through 50 °C, then derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C — a gentle slope that keeps the breaker usable in warm enclosures without oversizing the frame. At 130 mm tall and 4 in wide, this 4-pole MCCB fits standard US-pattern distribution panels and switchboard mounting — the 4 in width matches typical MCCB cutouts for high-density layouts. An undervoltage release is included, and a motor drive can be added as an optional extension for remote tripping or reset. ## Lifecycle and compliance posture The N-conductor is protected at 100% rating, meaning the neutral pole is fully rated for the same current as the phases — important for 4-wire systems with harmonic loads.","metaTitle":"Siemens 3VA1220-5EF32-0LC0 SENTRON MCCB, 80 A, 220 kA at 240","metaDescription":"Siemens 3VA1220-5EF32-0LC0 SENTRON 4-pole MCCB, 80 A rated continuous current, 220 kA breaking at 240 V.
