Breaking capacity hits 440 kA at 240 V, 330 kA at 415 V, and still 52.5 kA at 690 V, so it handles high-fault utility feeds or transformer secondaries without cascading upstream.","metaTitle":"Siemens 3VA2040-8HL32-0AA0 MCCB, 40 A, 3-Pole, 440 kA at 240","metaDescription":"Siemens SENTRON 3VA2040-8HL32-0AA0 molded case circuit breaker, 40 A continuous, 3-pole, ETU320 release, 440 kA at 240 V.
