That derating curve is the one to check if the breaker sits near other heat sources in a packed enclosure. That 110 mm depth is the dimension to watch when the breaker mounts in a shallow backpanel or against a gland plate — it fits standard SENTRON 3VA drawout and fixed-mount footprints, so a panel kitted for a 3VA frame will accept this unit without re-drilling.","metaTitle":"Siemens 3VA1332-6EF32-0DG0 SENTRON MCCB, 320 A, 3-Pole, 220","metaDescription":"Siemens SENTRON 3VA1332-6EF32-0DG0 molded case circuit breaker, 320 A, 3-pole, 220 kA at 240 V.
