The Siemens 3VA1116-4ED32-0AA0-ZD00 is a 3-pole IEC frame 160 circuit breaker from the 3VA1 series, with a breaking capacity class S rated at 36 kA at 415 V. It provides line protection via a fixed TM210 thermal-magnetic trip unit set at 160 A overload (Ir) and a fixed short-circuit protection (Ii) of 10 × In. The unit includes a nut keeper kit and is configured for DC Power OEM applications in China.
This breaker mounts on a DIN rail in a standard panel enclosure. The fixed thermal-magnetic trip eliminates field adjustment of the overload setting — Ir is locked at 160 A, so the breaker is sized for a specific load and should not be swapped into a circuit with a different full-load current. The 36 kA interrupting rating at 415 V means it can safely clear a fault up to that level without upstream cascading, which is typical for IEC distribution panels where the prospective short-circuit current is known.
