That flat thermal curve means no derating as the panel warms up; it holds 100 A at 70 °C just as it does at 40 °C. What it doesn't do: no overload protection, no short-circuit protection, no undervoltage release, no voltage trip, no communication function. It's a pure disconnect — a service-rated switch in an MCCB footprint, meant for isolation where the upstream device handles the fault interruption. Front-terminal busbar connection — this is the main circuit entry, not a box-terminal lug. That means it's designed for a busbar stack or plug-in feeder, not for landing field cables directly. The 101.6 mm width (4-pole) and 70 mm depth keep it within the standard SENTRON 3VA panel footprint; it shares the same 130 mm height as the rest of the 160-frame family. Three HQ auxiliary switches (changeover contacts) ride on the side, giving you status feedback without an add-on module. The IP40 front face is fine for a closed panel; no washdown rating here. Rated insulation voltage 800 V, operating voltage 690 V AC / 600 V DC. Max power loss 38 W — that's the heat it dumps into the enclosure at full rated current. Mechanical service life 15,000 operating cycles typical. The 100 A rating is flat across the entire operating temperature band — no derating curve to calculate.","metaTitle":"Siemens 3VA1110-1AA42-0AD0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens SENTRON 3VA1110-1AA42-0AD0 switch disconnector, 100 A continuous rating, 4-pole, busbar connection.
