At 415 V and 440 V it still holds 242 kA, and at 500 V it's 154 kA. ## Thermal derating — this is the real-world rating At 55 °C it drops to 313 A, at 60 °C to 306 A, at 65 °C to 299 A, and at 70 °C to 292 A. The maximum power loss is 80.1 W, which matters for enclosure heat load calculations in a sealed cabinet. ## Integration — panel fit and wiring The breaker measures 184 mm wide, 248 mm tall, and 110 mm deep. Front protection is IP40, so it's splash-safe from the front but not sealed against dust ingress through vents. No undervoltage release, no trip indicator, no communication module — this is a plain-vanilla thermal-magnetic breaker for straightforward line protection.","metaTitle":"Siemens 3VA1332-7FF42-0AA0 SENTRON MCCB, 160 A, 4-Pole, TM24","metaDescription":"Siemens 3VA1332-7FF42-0AA0 SENTRON molded case circuit breaker, 160 A fixed, 4-pole, TM240 release, 440 kA at 240 V.
