Rated current holds flat at 400 A from 40 °C up to 50 °C, then drops to 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, and 360 A at 70 °C. If the panel ambient sits at 55 °C, the breaker is good for 384 A continuous — no margin games. Maximum power loss is 66 W, which matters for ventilation in a sealed enclosure. ## Interrupting capacity by voltage At 240 V the breaker clears 187 kA; at 415 V and 440 V it clears 121 kA; at 500 V it clears 75.6 kA; at 690 V it clears 17 kA. ## Physical footprint That depth is the body only — add clearance for the UVR coil and auxiliary wiring.","metaTitle":"Siemens 3VA2440-5HL32-0CC0 SENTRON MCCB, 400 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0CC0 molded case circuit breaker, 400 A at 40 °C, 3-pole, ETU320 trip unit, 187 kA at 240 V.
