Rated insulation voltage Ui is 800 V, and maximum operational voltage reaches 690 V AC (50/60 Hz) or 500 V DC — so it's comfortable in 400 V or 480 V distribution panels and in DC bus circuits up to 500 V. The limited short-time withstand is 2 kA at both 1 s and 0.5 s intervals, which means this disconnector is intended for downstream isolation behind a higher-rated upstream protective device; it's not rated to break fault current on its own. The main current circuit connects via busbar connection with front terminals.","metaTitle":"Siemens 3VA1163-1AA32-0KC0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA32-0KC0 switch disconnector, 63 A rated continuous current, 3-pole, shunt trip STL 220-250 V DC / 208-277 V AC, 2 auxiliary switches HQ, IP40 front.

It lacks the factory shunt trip and auxiliary switches that this disconnector carries.
