The 400 A frame means the same physical breaker shell can be fitted with lower-rated trip units across the family, but this variant ships with the 40 A TM220 already installed. Interrupting capacity reaches 187 kA at 240 V AC and 121 kA at 415 V AC, dropping to 17 kA at 500 V AC. The 3VM1140-5EE42-0AA0 measures 130 mm high, 101.6 mm wide, and 70 mm deep. If you need remote tripping or status feedback, you'll add accessories externally or step to a 3VA series variant that supports those options. This part carries a current lifecycle stage — meaning Siemens still lists it as an active catalog number with no announced end-of-life. No successor has been published, so the 3VM1140-5EE42-0AA0 remains the direct order code for this rating and release combination.","metaTitle":"Siemens 3VM1140-5EE42-0AA0 SENTRON MCCB, 4P, 40A, TM220","metaDescription":"Siemens 3VM1140-5EE42-0AA0 SENTRON molded case circuit breaker, 4-pole, 40 A rated at 40 °C, TM220 release, 187 kA at 240 V.
