The 415 V figure is the one most panel builders will coordinate against for 400 V three-phase distribution — 75.6 kA gives headroom for high-fault service-entrance positions without cascading upstream. The TM240 release is a fixed thermal-magnetic type — no electronic adjustment or trip-indicator flag on this order code. The 50 A rating holds flat from 40 °C to 50 °C, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. In a sealed panel with internal ambient above 50 °C, size the continuous load at 45 A to avoid nuisance tripping. Dimensions: 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON and third-party distribution blocks without re-drilling the mounting plate.","metaTitle":"Siemens 3VA1150-4EF36-0DA0 SENTRON MCCB, 50 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1150-4EF36-0DA0 molded case circuit breaker, 3-pole, 50 A rated at 40 °C, 121 kA breaking capacity at 240 VAC.

The key difference is the overcurrent release: the 3VA1150-4EF36-0DA0 carries a TM240 release rated 50 A, while the 3VA1110-5EF32-0LA0 uses a different trip unit. Verify the continuous load rating and coordination study before swapping — the breaker will bolt in, but the protection settings may not match the original design."},{"question":"What compliance documentation is available for this MCCB?","answer":"As a Siemens SENTRON product, the 3VA1150-4EF36-0DA0 is designed to meet IEC 60947-2 and UL 489 standards for molded case circuit breakers.
