The adjustable thermal-magnetic trip unit covers 600–4800 A, so one frame size handles a wide range of downstream loads — useful when the BOM needs to freeze a single part number across multiple panel builds. Interrupting capacity reaches 242 kA at 240 V AC and 187 kA at 415/440 V, dropping to 121 kA at 500 V and 9 kA at 690 V. That stack covers remote status indication and emergency-off integration without adding external relay logic. The shunt trip is factory-installed; verify coil voltage against the panel control voltage before wiring. No undervoltage release, ground-fault monitoring, or communication module is fitted on this order code. If those functions are required on the customer's AML, a different 3VA2 suffix or an external add-on module would need a deviation request. Depth of 110 mm includes the rotary handle projection; allow clearance for cable bending radius below the line-side lugs. Maximum power dissipation is 63.5 W at rated load. In a sealed enclosure, that heat must be factored into the thermal budget — a vented or fan-cooled panel is advisable if multiple breakers are ganged.","metaTitle":"Siemens 3VA2440-6HL32-0HL0 SENTRON MCCB, 400 A, 600–4800 A t","metaDescription":"Siemens SENTRON 3VA2440-6HL32-0HL0 molded case circuit breaker, 400 A continuous at 40 °C, adjustable trip 600–4800 A, 242 kA at 240 V.
