The Siemens SENTRON 3VA2440-7HL32-0KA0 is a 3-pole molded case circuit breaker rated for 400 A continuous current (Iu) at 40 °C through 50 °C, derating to 360 A at 70 °C. That 400 A frame covers main feeders or large motor branch circuits in industrial switchgear. Breaking capacity runs 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. At 415 V — common in European industrial panels — that 242 kA interrupting rating handles high-fault scenarios without cascading upstream breakers. The supplied basic switch carries order code 3VA2440-7HL32-0AA0, and the integrated auxiliary trip is 3VA9688-0BL33. No auxiliary contacts are fitted as standard.
Panel builders should account for the 63.5 W maximum power loss when sizing enclosure ventilation.
