The 400 A rating holds steady up to 50 °C ambient; above that it derates to 392 A at 55 °C, 384 A at 60 °C, 376 A at 65 °C, and 367 A at 70 °C — so if your panel runs hot, you need to account for the drop. It is a line-protection design (not a motor-protector or a switch-disconnector), so it is intended for feeder and main breaker duty in distribution panels.","metaTitle":"Siemens SENTRON 3VA1340-4EE32-0AA0 MCCB, 400 A, 3-Pole, TM22","metaDescription":"Siemens SENTRON 3VA1340-4EE32-0AA0 molded case circuit breaker, 400 A continuous, 3-pole, TM220 trip unit, 121 kA at 240 V.
