Three-pole construction, TM210 thermal-magnetic release. The TM210 is a fixed thermal, fixed magnetic trip — no adjustment dials, which simplifies spec but means the breaker is matched to a specific load current at order time. Interrupting capacity is the headline here: 220 kA at 240 V AC, 154 kA at 415 V, 121 kA at 440 V, still 17 kA at 690 V. The 17 kA at 690 V means it can also serve 690 V distribution in regions where that is standard, though the high-end interrupting drops sharply above 500 V. ## Sourcing & Lifecycle — Current Production Rated insulation voltage 800 V, front-side IP40 protection (finger-safe from the front, but the back and sides are open to the panel environment). Power loss 10.8 W maximum at rated load — plan for that heat in the enclosure thermal budget. Width 76.2 mm (3 in), depth 70 mm (2.76 in), height 130 mm (5.12 in). Standard MCCB footprint for the 40 A frame class. Mounts via screw-clamp to a backplate or DIN-rail adapter (not included). The 3-pole width means it occupies three 25.4 mm pole spaces — typical for this class.","metaTitle":"Siemens 3VA1140-6ED32-0AA0 SENTRON MCCB, 40 A, 3-Pole, TM210","metaDescription":"Siemens SENTRON 3VA1140-6ED32-0AA0 molded case circuit breaker, 40 A rated, 3-pole, TM210 release.
