Rated for 690 V AC and 500 V DC, it covers common industrial voltage bands for motor feeder isolation, bus coupler switching, or transformer primary disconnection. At 76.2 mm wide, 130 mm tall, and 70 mm deep, this occupies a standard 3-pole MCCB footprint on the DIN rail or mounting plate — the same cutout as a 3VA1 breaker of the same frame, so a panel laid out for a 3VA1 MCCB accepts this switch disconnector without re-drilling. The front terminal arrangement with busbar connection means it is intended for vertical busbar systems or plug-in distribution blocks, not for direct cable entry. Plan for busbar adapters or a distribution block upstream. ## Built-in accessories — shunt trip and auxiliary switches The three CO (changeover) contacts for auxiliary switching give you one spare set beyond the standard NO+NC for status feedback, useful if you need both a PLC input and a panel lamp without adding an interposing relay.","metaTitle":"Siemens 3VA1110-1AA32-0JH0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens SENTRON 3VA1110-1AA32-0JH0 MCCB-style switch disconnector, 100 A rated continuous current, 3-pole, 690 V AC / 500 V DC.
