It includes an undervoltage release at 24 V DC and two auxiliary switches. The 100 A continuous rating (Iu) defines the maximum current the switch can carry without exceeding temperature limits — sized for a feeder or main disconnect on a 100 A branch. The UVR at 24 V DC provides undervoltage protection: if the control voltage drops, the switch trips open. This is a common requirement for motor circuits where loss of control voltage must disconnect the load. The two auxiliary switches (2 CO contacts) give you status feedback for a PLC or indication lamp. The busbar connection and front terminal arrangement mean it's designed for panel mounting with busbar systems — not for DIN-rail clip-on.","metaTitle":"Siemens 3VA1110-1AA32-0BC0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens 3VA1110-1AA32-0BC0 SENTRON switch disconnector, 100 A rated continuous current, 3-pole, 690 V AC / 500 V DC, with undervoltage release 24 V DC and 2 auxiliary switches.
