The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V, giving you selectivity headroom across common distribution voltages. The 3VA2440-5HL32-0AJ0 measures 248 mm high by 138 mm wide by 110 mm deep. The auxiliary contact version (2 switches + 1 trip alarm) is already populated on the basic switch 3VA2440-5HL32-0AA0. If your BOM calls for separate alarm or status feedback, this variant saves an add-on module slot.","metaTitle":"Siemens 3VA2440-5HL32-0AJ0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0AJ0 molded case circuit breaker, 400 A at 40 °C, 3-pole, ETU320 release, 187 kA at 240 V.
