It provides visible-break isolation with no overload or short-circuit protection built in, so it's a dedicated disconnecting means, not a circuit breaker. That 600 V DC rating makes it usable in battery or DC-bus isolation applications where many AC-only disconnects can't go. Front terminals accept busbar connections, and the IP40 front protection keeps finger contact out during normal panel access. ## Auxiliary switching and mechanical life Mechanical service life is 15 000 operating cycles, typical for a disconnect used in maintenance isolation rather than daily motor starting.","metaTitle":"Siemens 3VA1163-1AA42-0AH0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens 3VA1163-1AA42-0AH0 SENTRON switch disconnector, 63 A at 40-70°C, 4-pole, IP40 front, 70 mm depth.
