Rated continuous current Iu of 63 A means this switch disconnector carries 63 A indefinitely without exceeding temperature rise limits — sized for a 63 A feeder or a motor load drawing up to that current. The 15 000 latching-endurance cycles (mechanical) cover frequent manual switching in a maintenance disconnect role, though not daily production cycling. When supply voltage falls below about 70-80% of rated, the release trips the mechanism open. No leading contact on the UVR (: No), so the release does not anticipate the main pole closure — the switch must be manually reset after a voltage dip. The IP40 front protection means it's dust-protected but not washdown-rated; install inside a panel with a door. In a densely packed panel, that 38 W per unit adds to the thermal budget; allow ventilation or spacing around the 70 mm depth × 101.6 mm width × 130 mm height footprint. Main circuit connection is busbar connection at the front terminals, so it's designed for horizontal busbar distribution in a panelboard or switchboard lineup. No auxiliary contacts are fitted (: Without), so there's no remote status feedback unless you add the optional auxiliary switch kit (product extension optional motor drive available per). The IP40 front face keeps tools and fingers out but doesn't seal against hose-down — keep it behind a panel door in washdown zones.","metaTitle":"Siemens 3VA1163-1AA42-0DA0 SENTRON Switch Disconnector, 63A,","metaDescription":"Siemens SENTRON 3VA1163-1AA42-0DA0 switch disconnector, IEC frame 160, 4-pole SD100, 63 A rated continuous current, undervoltage release 208-230 V AC.

No overload or short-circuit protection is built in, so it's a disconnect for safety isolation, not a circuit breaker."},{"question":"What are the key ratings of 3VA1163-1AA42-0DA0?","answer":"Rated continuous current Iu = 63 A; max AC operational voltage Ue = 690 V 50/60 Hz; rated insulation voltage Ui = 800 V; 4 poles; undervoltage release 208-230 V AC; IP40 front protection; 70 mm depth × 101.6 mm width × 130 mm height."},{"question":"Where can I buy 3VA1163-1AA42-0DA0?","answer":"This part is sourced to order against an RFQ through independent distribution.

It is a switch disconnector for isolation only — you need an upstream circuit breaker or fuse for fault protection."},{"question":"What voltage does the undervoltage release need?","answer":"The undervoltage release (UVR) is rated for 208-230 V AC 50/60 Hz.
