These ratings are for AC networks; for DC applications, consult the 3VA device manual. Above that, the continuous current drops linearly: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. Front IP40 protection means it is suitable for general indoor panel environments but not washdown areas. Dimensions are 76.2 mm wide, 130 mm high, 70 mm deep — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration. The 3VA1140-5EF36-0AB0 is a current-production Siemens SENTRON MCCB.","metaTitle":"Siemens 3VA1140-5EF36-0AB0 SENTRON MCCB, 40 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA1140-5EF36-0AB0 SENTRON molded case circuit breaker, 40 A rated, 3-pole, TM240 release, 187 kA at 240 V.
