It's built for applications where you need a certified disconnect point without the trip curve of a molded case breaker. ## Undervoltage release and control wiring Includes an undervoltage release (UVR) that trips the disconnector when control voltage drops. No auxiliary contacts, voltage trigger, or communication function are present. The main circuit connects via busbar connection at the front terminals. An optional motor drive can be added for remote switching. Front protection is IP40.","metaTitle":"Siemens 3VA1110-1AA42-0BA0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens 3VA1110-1AA42-0BA0 SENTRON switch disconnector, 100 A rated current, 4-pole, undervoltage release 24 V DC, IP40 front, current production.
