That is unusual for an MCCB-style device; most need a derate above 40 °C. For a panel running warm (say 50 °C interior), you still get the full 63 A. Short-time withstand: limited to 1 s at 2 kA, and also rated 2 kA for 0.5 s AC. That is a modest fault rating — this is a switch disconnector, not a full-rated MCCB for high-fault service. It is sized for isolation and switching under load, not for interrupting high-level faults. Pair it with upstream protection (fuse or MCCB) rated for your available fault current. Power loss is 38 W maximum at rated current. No communication function on this unit; it is a standalone disconnect.","metaTitle":"Siemens 3VA1163-1AA42-0DH0 SENTRON 4P Switch Disconnector, 6","metaDescription":"Siemens SENTRON 3VA1163-1AA42-0DH0 4-pole switch disconnector, 63 A rated continuous current, 690 V AC / 600 V DC.
