The 32 A rating holds across ambient temperatures up to 50 °C; above that it derates gradually to 28.8 A at 70 °C, which matters for panels running warm near the top of the enclosure. The 3VA1132-3EF32-0AF0 measures 76.2 mm wide, 130 mm high, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling. Front IP40 protection covers the operator interface; the rest of the device is designed for enclosed panel mounting. For a site electrical engineer working on selectivity: the TM240 trip unit is fixed (not adjustable), so coordination with downstream breakers depends on the time-current curve of this specific thermal-magnetic release.","metaTitle":"Siemens 3VA1132-3EF32-0AF0 SENTRON MCCB, 32 A, 3-Pole, Line","metaDescription":"Siemens 3VA1132-3EF32-0AF0 SENTRON molded case circuit breaker, 32 A rated, 3-pole, TM240 trip unit, breaking capacity 75.6 kA at 240 V.
