It carries 690 V AC and 500 V DC operating voltage, with an insulation voltage rated at 800 V. The built-in undervoltage release (UVR) is wound for 208-230 V AC 50/60 Hz, which drops the load if control power is lost — useful for safety isolation or emergency-stop circuits where a maintained disconnect is required. The 100 A rating is flat to 70 °C — no thermal headroom lost as ambient climbs, which is unusual for a molded-case device and simplifies panel coordination. The UVR (undervoltage release) is the only auxiliary release fitted; there are no auxiliary switches or communication functions on this variant. Front terminal connections with clamp terminals accept standard copper cable. Front terminal access means wiring from the front without reaching behind the panel. The UVR coil draws its control voltage from a separate 208-230 V AC circuit; verify the control transformer taps before commissioning.","metaTitle":"Siemens 3VA1110-1AA36-0DA0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens 3VA1110-1AA36-0DA0 SENTRON switch disconnector, 100 A rated current, 3-pole, 690 V AC / 500 V DC.

Both share the same 76.2 mm width, 130 mm height, and 70 mm depth, so the mechanical footprint is identical. However, the 5ED36 variant has box terminals on both sides versus the clamp terminals on the 1AA36, and the auxiliary switch wiring differs — verify terminal arrangements before swapping."},{"question":"What compliance documentation does this brand provide for 3VA1110-1AA36-0DA0?","answer":"As a Siemens SENTRON product, the 3VA1110-1AA36-0DA0 carries the standard IEC 60947-3 classification for switch-disconnectors.
