Rated insulation voltage (Ui) is 800 V, with maximum operational voltage 690 V AC 50/60 Hz and 500 V DC. The 100 A rating and 3-pole configuration suit it for isolating three-phase motor feeders, panel incoming sections, or distribution sub-circuits where a visible break is required for lockout/tagout. Four HQ auxiliary contacts (4 CO) are built in, giving status feedback for PLC inputs or panel indication without needing a separate aux block. ## What the 100 A rating means for fit For a switch disconnector, the key distinction from a circuit breaker is that this part is designed to make and break load currents (up to its rated operational voltage) but not to interrupt fault currents. It is sized for the full-load current of the downstream load, not for available fault current. The 2 kA limited short-time withstand (1 s and 0.5 s ratings) confirms it can survive a fault current of that magnitude for the stated duration while the upstream protective device clears — typical for a downstream isolator in a selectively coordinated distribution system. The 3VA1110 frame shares the same 70 mm depth, 76.2 mm width, and 130 mm height as other 3VA1 IEC frame 160 three-pole devices. The front terminal arrangement accepts busbar connection with the included nut keeper kit — no lug or box terminal conversion needed for busbar feed. Maximum power dissipation at rated current is 38 W — account for this in panel thermal calculations if the switch is enclosed with other heat sources.","metaTitle":"Siemens 3VA1110-1AA32-0AE0 Switch Disconnector, 100 A, 3-Pol","metaDescription":"Siemens SENTRON 3VA1110-1AA32-0AE0 switch disconnector, 100 A rated continuous current, 3-pole, 4 HQ auxiliary switches, IP40 front.

Both share the same 3-pole frame 160 footprint, 100 A rating, and front terminal arrangement, so the switch disconnector can drop into the same panel position as the MCCB — but it does not provide the same protection function. The MCCB also carries 2 auxiliary switches (vs. 4 on the switch disconnector) and has a higher mechanical endurance of 20,000 cycles vs. 15,000."},{"question":"Where can I buy 3VA1110-1AA32-0AE0?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
