Interrupting capacity is 187 kA at 240 V, dropping to 121 kA at 415 V and 9 kA at 690 V. At 690 V the 9 kA rating is lower than some, so check your system's prospective fault level if you're running 690 V. That gives you remote tripping capability and status feedback without adding external relays. The basic switch core is order code 3VA2440-5HL32-0AA0.","metaTitle":"Siemens 3VA2440-5HL32-0KH0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0KH0 molded case circuit breaker, 400 A continuous at 70 °C, 187 kA at 240 V.
