The Siemens 3VA1163-4EF32-0AA0-ZD00 is a 3-pole IEC frame 160 molded case circuit breaker with a 63 A fixed thermal-magnetic trip unit (TM240) and a breaking capacity class S rated at 36 kA at 415 V. The overload protection (Ir) is adjustable from 44 A to 63 A, and the short-circuit protection (Ii) is set at 5 to 10 times In. This variant includes a nut keeper kit and is configured for a DC Power OEM in China.
Mounts on a DIN rail or panel in a standard distribution enclosure. The 36 kA breaking capacity at 415 V gives headroom for most industrial fault levels without cascading upstream.
