Breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V, so it handles high-fault utility feeds and transformer-secondaries common in North American and European industrial panels. The TM210 thermal-magnetic trip unit gives fixed thermal and magnetic settings — no adjustment dials, which means fewer setup errors on the line but also no field tweaking if the load changes. At 240 V the 75.6 kA interrupting rating puts this MCCB well above typical service-entrance fault levels for most industrial and commercial panels — you get full selectivity with upstream fuses or a larger-frame SENTRON without worrying about cascade failure. At 415 V the 52.5 kA still covers heavy industrial transformer feeds; at 690 V the 11.9 kA rating is adequate for downstream sub-distribution but not for main incomer duty on a high-power VFD bus. ## Thermal performance and power loss The IP40 front protection means it is splash-safe from the front but not sealed against hose-down; mount it in a panel with proper gasketing if the environment is wet. At 130 mm high, 76.2 mm wide, and 70 mm deep, this breaker fits the standard 3-pole SENTRON 3VA footprint. The TM210 trip unit is fixed; if you need adjustable thermal or magnetic pickup later, you are looking at a different variant (the 3VA1112-5EE32-0AA0, for instance, carries an electronic trip unit).","metaTitle":"Siemens 3VA1112-3ED36-0AA0 SENTRON MCCB, 125A, 75.6kA","metaDescription":"Siemens SENTRON 3VA1112-3ED36-0AA0 molded case circuit breaker, 3-pole, 125A rated at 40°C, 75.6kA breaking at 240V.
