It handles 690 V AC and 600 V DC, with busbar connection and front terminals. ## Ratings that matter for the install That -25 °C floor matters for unheated electrical rooms in cold climates; the part will switch reliably without condensation issues down to that point. Width at 101.6 mm is roughly 4 inches. The switch disconnector has no undervoltage release and no voltage trigger — it's a straight manual isolator with a trip-indicator flag. If you need undervoltage protection or a shunt trip, you'd add an external release module (the optional motor-drive extension is listed as available).","metaTitle":"Siemens SENTRON 3VA1110-1AA42-0AF0 4-Pole Switch Disconnecto","metaDescription":"Siemens SENTRON 3VA1110-1AA42-0AF0 MCCB-design switch disconnector. 4-pole, 100 A rated continuous current, 690 V AC / 600 V DC.
