It serves as a manual load-break disconnect for isolating circuits under load, with no overcurrent or short-circuit protection built in — that is, it is a switch, not a breaker. The front terminal connection accepts copper conductors for panel wiring, and the IP40 front protection keeps dust and tools out of the live parts inside the enclosure. The unit occupies a 76.2 mm wide footprint.
The 63 A rated continuous current (Iu) sets the maximum load the switch can carry continuously. The short-circuit making capacity is 2 kA.
Where It Goes — Deployment Context
This switch disconnector is designed for mounting in a low-voltage switchgear or distribution panel. Front terminals simplify wiring access during panel build and maintenance. Typical applications include main incoming isolation for sub-distribution boards and machine tool disconnect switches. The UVR makes it suitable for undervoltage protection.
For buyers needing to fill a BOM line or replace a failed unit, the 3VA1163-1AA36-0DH0 is a direct drop-in for any panel designed around the 3VA frame 160 switch disconnector family. The front terminal connection and auxiliary contact configuration are specified at order — verify the UVR voltage (208-230 V AC) matches the control supply before ordering.
