The Siemens 3VA1110-1AA36-0KH0 is a SENTRON 3VA1 switch disconnector in an MCCB-style housing — three poles, rated 100 A continuous, with no overload or short-circuit protection built in. That means it functions purely as a load-break disconnect: you use it where isolation and switching are the job, not overcurrent protection. The 100 A rating holds flat from 40 °C all the way up to 70 °C, so no derating headache in a warm panel. It ships with a shunt trip release (STL) wired for 220–250 V DC or 208–277 V AC, plus two HQ auxiliary switches and one trip alarm switch — three CO contacts total. The front-facing clamp terminals accept standard copper conductors, and the 70 mm depth fits the 3VA1 frame footprint. Rated insulation voltage is 800 V; operating voltage goes to 690 V AC or 500 V DC.
Mounts in a standard distribution board or control panel on a mounting plate — the 76.2 mm width and 130 mm height match the 3VA1 MCCB cutout. Front terminals keep wiring accessible without pulling the unit.
