This is a line-protection version, not a motor-protection variant with adjustable thermal curves. The 320 A rating holds flat from 40 °C to 50 °C, then derates to 292 A at 70 °C — so in a hot enclosure you lose about 9% of headroom. Front IP40 means it's splash-safe from the front but not sealed; mount it inside a cabinet, not outdoors. ## Fit and integration notes That's a standard MCCB footprint — it bolts into a panel busbar system or mounts on a backplate with the supplied hardware. No communication module onboard — this is a standalone breaker, not a smart metering device.","metaTitle":"SENTRON 3VM1332-5GE42-0AA0 Molded Case Breaker, 320 A, 187 k","metaDescription":"SENTRON 3VM1332-5GE42-0AA0 4-pole molded case circuit breaker, 320 A rated continuous current, 187 kA breaking at 240 V.
