This is a standard MCCB for feeder or main breaker duty in commercial and industrial switchboards. Interrupting capacity is strong: 121 kA at 240 V AC, 76 kA at 415 V AC and at 440 V AC, and 53 kA at 500 V AC. For DC systems, Siemens directs you to the 3VA Molded Case Circuit Breaker Manual for the specific DC switching capacity values. Above that, the continuous current must be reduced: 392 A at 55 °C, 384 A at 60 °C, 376 A at 65 °C, and 367 A at 70 °C. The breaker itself dissipates up to 92 W at full load, which contributes to the enclosure heat rise.","metaTitle":"Siemens 3VM1340-4ED32-0AA0 SENTRON MCCB, 400 A, 3-Pole, TM21","metaDescription":"Siemens SENTRON 3VM1340-4ED32-0AA0 molded case circuit breaker, 400 A continuous at 40 °C, 3-pole, TM210 release, 121 kA at 240 V AC.
