The front terminal accepts busbar connection, and the IP40 front face suits enclosed panel mounting where occasional front access is needed. The 690 V AC / 500 V DC rated operating voltage covers standard 400 V three-phase distribution and many DC bus circuits. Rated insulation voltage at 800 V gives headroom for systems with transient overvoltages up to that level. This is a switch disconnector, not a circuit breaker — there is no overload or short-circuit protection built in. It's intended for isolation and switching under load where the upstream protective device handles fault clearing. ## Panel integration The 76.2 mm width matches the standard 3-pole MCCB footprint for the SENTRON 3VA1 frame 160. Depth of 70 mm and height of 130 mm fit typical DIN-rail or backplate layouts. Front terminals accept busbar connection — plan for busbar routing rather than individual lug terminations. The IP40 front face is fine for enclosed panels; keep it out of direct washdown zones. The shunt trip coil draws power only during the trip event; no continuous hold current. Verify the control voltage matches your system: 12-30 V DC or 24 V AC. The two auxiliary switches are pre-wired with CO contacts — one set for status, one for interlock logic, no extra aux block to buy.","metaTitle":"Siemens 3VA1110-1AA32-0HC0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens SENTRON 3VA1110-1AA32-0HC0 switch disconnector, 100 A rated at 40-70 °C, 3-pole, shunt trip STL 12-30 V DC / 24 V AC, 2 HQ aux switches, IP40 front.

The key difference: the 3VA1010-2ED32-0JA0 is a molded case circuit breaker with overcurrent protection, while the 3VA1110-1AA32-0HC0 is a switch disconnector without protection. The wiring interface is different: the breaker uses lug terminals, the disconnector uses busbar connection. You cannot simply swap one for the other without reviewing the circuit protection scheme and busbar layout."},{"question":"Where can I buy 3VA1110-1AA32-0HC0?","answer":"This part is sourced to order through independent distribution channels.
