Interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 52.5 kA at 690 V, giving selectivity headroom for high-fault panels downstream of a large transformer.","metaTitle":"Siemens 3VA1580-5EF32-0CA0 SENTRON MCCB, 800 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA1580-5EF32-0CA0 molded case circuit breaker, 3-pole, 800 A at 40 °C, 187 kA interrupting at 240 V.
