The 4800 A frame rating means the breaker's internal mechanism and contact structure are built for that maximum current; the actual trip unit sets the continuous rating. Breaking capacity is what decides whether this breaker clears a fault without upstream coordination failure: 242 kA at 240 V, 187 kA at 415 V, 121 kA at 500 V, and 9 kA at 690 V. At 415 V it handles 187 kA — that is well into high-fault-current industrial distribution, so it will hold its own on large transformer secondaries or near utility tie-ins. ## Line protection configuration This variant is designated for line protection — the basic switch version is 3VA2440-6HN32-0AA0. It ships without auxiliary switches or ground-fault monitoring, but includes a shunt trip (STL) undervoltage release. No communication function or trip indicator on this build; if remote signaling or status feedback is needed, order the version with the auxiliary switch block. ## Physical integration Panel builders should verify the handle clearance and arc-chamber venting per Siemens mounting guidelines; the breaker requires no side clearance for derating if ambient is within the rated 70 °C limit.","metaTitle":"Siemens 3VA2440-6HN32-0JA0 SENTRON MCCB, 400 A, 4800 A max","metaDescription":"Siemens SENTRON 3VA2440-6HN32-0JA0 molded case circuit breaker, 400 A rated at 40-70 °C, 4800 A frame, 242 kA at 240 V.
