Its interrupting capacity hits 121 kA at 240 VAC and 75.6 kA at 415 VAC — numbers that govern selectivity coordination in high-fault panels, not just the branch rating. ## Current derating across temperature The breaker holds 80 A continuously 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. For a panel running warm — say near the top of a crowded enclosure — the 65 °C column (75 A) is the real continuous rating to use for load planning. The 3VA1180-4EE36-0AA0 measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard SENTRON 3VA footprint that mounts directly to a backplate or DIN rail via the integrated clip. Front-face protection is IP40, sufficient for enclosed panel use but not for washdown environments. The 3-pole design occupies a single modular width; no communication module or voltage-trip accessory is included, so the wiring bay stays clean for the power conductors only.","metaTitle":"Siemens 3VA1180-4EE36-0AA0 SENTRON MCCB, 80 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1180-4EE36-0AA0 molded case circuit breaker, 80 A rated, 121 kA interrupting at 240 VAC, 3-pole, TM220 release.
