Above that it derates linearly: 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, 45 A at 70 °C. In a sealed, uncooled enclosure — say a steel panel in a plant mezzanine — the internal ambient can easily hit 55 °C, so plan for the 49 A ceiling rather than the catalog 50 A. The supplied basic switch is 3VA11506EF320AA0, and the auxiliary switch configuration is two HQ-style switches, so if the panel design calls for remote status indication, those contacts are already there.","metaTitle":"SENTRON 3VA1150-6EF32-0AC0 MCCB, 50 A, 220 kA at 240 V","metaDescription":"SENTRON 3VA1150-6EF32-0AC0 molded case circuit breaker, 50 A rated, 3-pole, line protection, TM240 release, 220 kA breaking capacity at 240 V.
