It provides no overload or short-circuit protection — its role is safe isolation and disconnection under load, not fault clearing. The built-in undervoltage release (UVR) at 24 V DC automatically opens the switch when control voltage drops, a standard requirement for emergency-stop and safety circuits. The 2 kA limited short-time withstand (1 s and 0.5 s) means it can survive a fault current of that magnitude while the upstream protective device clears — it is not a circuit breaker and must be coordinated with a fuse or MCCB upstream. The switch disconnector uses busbar connection on the front terminals for the main circuit — designed for panel-mount with busbar links, not cable lugs. Dimensions are 70 mm deep, 101.6 mm wide, 130 mm high, fitting the standard 3VA1 frame 160 footprint. IP40 front protection means it is suitable for enclosed panel installation, not open washdown areas.","metaTitle":"Siemens 3VA1163-1AA42-0BC0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA42-0BC0 switch disconnector, 4-pole, 63 A rated continuous current, 690 V AC / 600 V DC.
