The 160 A continuous rating holds flat from 40 °C up to 50 °C, then derates stepwise: 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, and 142 A at 70 °C. The interrupting ratings across voltage levels are what decide whether this breaker clears a fault without rupturing: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V. ## Panel fit and physical constraints The 3VA1216-4EF42-0AA0 measures 158 mm high, 140 mm wide, and 70 mm deep — a 4-pole MCCB that fits standard distribution panel footprints.","metaTitle":"Siemens 3VA1216-4EF42-0AA0 SENTRON MCCB, 160 A, 4-Pole, TM24","metaDescription":"Siemens 3VA1216-4EF42-0AA0 SENTRON molded case circuit breaker, 160 A continuous, 4-pole, TM240 thermal-magnetic release.
