That covers most line-level disconnects and DC bus isolation in industrial panels. The front terminal connection accepts lug or clamp conductors, and the IP40 front protection keeps debris out of the enclosure face — standard for panel-mounted gear, not for washdown zones. ## Undervoltage release and auxiliary contacts If the control voltage drops, the UVR trips the disconnector open — a standard safety interlock for emergency-stop chains or undervoltage protection on motor feeds. No communication module on this unit — it's a hardwired disconnect, not a smart breaker. Maximum power dissipation is 38 W at rated load.","metaTitle":"Siemens 3VA1163-1AA36-0BC0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA36-0BC0 switch disconnector, 63 A rated continuous current, 3-pole, IEC frame 160.
