Breaking capacity reaches 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V, so it handles high-fault utility feeds and transformer secondaries without cascading upstream. The line-protection design (no ground-fault module) keeps the trip curve focused on overload and short-circuit clearing for distribution feeders or large motor branch circuits. ## Panel fit and auxiliary complement At 110 mm deep, 138 mm wide, and 248 mm tall, this MCCB occupies a standard SENTRON 3VA mounting footprint — the same bolt-hole pattern as other 3VA2 frame sizes, so a panel laid out for a 400 A SENTRON accepts this unit without re-drilling. Maximum power loss is 66 W at rated current. In a sealed enclosure, that heat must be vented or the internal ambient kept below 70 °C (the operating maximum) and above -25 °C (the operating minimum). The 5 kA limited-to-1-second rating is a short-time withstand figure for selective coordination — useful when this breaker feeds a downstream panel and you need the upstream device to hold during a fault.","metaTitle":"Siemens 3VA2440-6HN32-0CL0 SENTRON MCCB, 400 A, 4800 A frame","metaDescription":"Siemens SENTRON 3VA2440-6HN32-0CL0 molded case circuit breaker, 400 A rated at 40-70°C, 4800 A frame, 242 kA at 240 V.
