Rated operational voltage is 415 V AC, with a maximum DC rating of 250 V. Current rating holds flat at 40 A from 40 °C up to 50 °C, then derates to 39 A at 55 °C and 60 °C, and 38 A at 65 °C, with 37 A at 70 °C. That's a shallow derate curve — useful if the breaker lives near other heat sources in a crowded enclosure. ## Dimensions & Panel Fit The 3VM1140-3ED22-0AA0 measures 70 mm deep, 50.8 mm wide, and 130 mm tall. That 50.8 mm (2 in) width is a standard 2-pole MCCB footprint — it drops into a panel cutout sized for that pitch without modification. Depth of 70 mm leaves room for rear bus connections in a typical 200 mm deep enclosure. ## Trip Unit & Protection The TM210 thermal-magnetic trip provides fixed thermal and magnetic settings — no adjustable long-time or short-time pickup. The magnetic instantaneous pickup is set at 400 A (10× In). It's a straight line-protection breaker for simple distribution.","metaTitle":"Siemens 3VM1140-3ED22-0AA0 SENTRON MCCB, 40 A, 2-Pole, 76 kA","metaDescription":"Siemens 3VM1140-3ED22-0AA0 SENTRON molded case circuit breaker, 40 A, 2-pole, TM210 trip, 76 kA at 240 V AC, 53 kA at 415 V AC.
