It provides no overload or short-circuit protection — this is a pure isolating switch for load-break and visible disconnect applications, not a circuit breaker. The 63 A rated continuous current (Iu) is the maximum uninterrupted load this switch can carry in free air at 40 °C ambient — sized for a 30–50 A motor feeder or a 63 A resistive load branch where isolation, not overcurrent protection, is the function. The short-time withstand rating of 2 kA at 1 s (and at 0.5 s) tells you the switch can survive a fault current of that magnitude for that duration while closed; upstream protection must clear before the limit is exceeded. The 15 000 mechanical endurance cycles are typical for a panel-main disconnect, not a daily-operating contactor. Mounts in the standard 3VA1 frame footprint: 70 mm deep, 76.2 mm wide, 130 mm tall — same cutout and drilling pattern as the 3VA1 MCCB line, so it drops into an existing panel layout without rework. The 4 HQ auxiliary switches (4 CO) are factory-fitted and wired to the front terminal block; no separate order for aux contacts. The undervoltage release is not present (no UVR), and no communication module is installed — this is a standalone disconnect. A motor drive can be added as an optional extension (field-fit).","metaTitle":"Siemens 3VA1163-1AA36-0AE0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA36-0AE0 switch disconnector, 63 A rated continuous current, 3-pole, 690 V AC / 500 V DC, IP40 front, 4 HQ auxiliary switches.
