Its interrupting capacity hits 121 kA at 240 V, dropping to 75.6 kA at 415 V and 52.5 kA at 440 V — enough headroom for high-fault utility feeds or transformer secondaries in industrial distribution. Panel footprint: 140 mm wide, 158 mm tall, 70 mm deep. The 4-pole design with 50% N-conductor protection handles three-phase plus neutral in a single unit, saving a separate neutral breaker slot. Thermal derating starts at 55 °C — at 70 °C the continuous rating drops to 142 A.","metaTitle":"Siemens 3VA1216-4FF42-0AA0 SENTRON MCCB, 160 A, 4-Pole, 121","metaDescription":"Siemens 3VA1216-4FF42-0AA0 SENTRON molded case circuit breaker, 160 A continuous, 4 poles, 121 kA at 240 V.
