Its TM210 thermal-magnetic release provides overload and short-circuit protection for feeder and distribution circuits in industrial switchboards and panelboards. The interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415 V, and 75.6 kA at 440 V — figures that cover most low-voltage fault scenarios without requiring upstream current-limiting fuses. ## Breaking Capacity and Thermal Performance The thermal derating curve is documented: full 100 A up to 50 °C, then 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. For panel builders, this means no forced derating in a standard 40 °C enclosure, but a 9 % reduction if the internal ambient reaches 70 °C. ## Physical Dimensions and Panel Integration The breaker occupies a 76.2 mm width (3 in), 130 mm height (5.12 in), and 70 mm depth (2.76 in). This 3-pole footprint matches the standard SENTRON 3VA molded-case envelope, allowing direct replacement within the same family without re-drilling the mounting plate or re-routing busbars. The depth of 70 mm clears most shallow gland-plate enclosures, though the rear-mounted terminals require at least 50 mm of bending radius for 70 mm² cable lugs. Maximum power loss is 25 W at rated current — relevant for thermal calculations inside sealed cabinets. ## Auxiliary Switching and Release Configuration This variant ships with four HQ-type auxiliary switches (two form-C contacts each, configurable for status indication or remote tripping) and the basic switch 3VA11105ED320AA0. The rated insulation voltage is 800 V, and the operating temperature range spans -25 °C to 70 °C, with storage from -40 °C to 80 °C.","metaTitle":"Siemens 3VA1110-5ED32-0AE0 SENTRON MCCB, 100 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1110-5ED32-0AE0 molded case circuit breaker, 100 A rated at 40 °C, 3-pole, 187 kA breaking at 240 V.
