Siemens 3VA1032-4ED32-0AA0-ZD00 Circuit Breaker, 32A, 36kA @

The 3VA1032-4ED32-0AA0-ZD00: This is a Siemens 3VA1 IEC frame 100 circuit breaker, breaking capacity class S, with a rated ultimate short-circuit breaking capacity Icu of 36 kA at 415 V AC. The 32 A fixed thermal overload (Ir) and fixed magnetic short-circuit release set at 10 x In (320 A) suit it for line protection on a 32 A feeder, not for adjustable motor overload duty. The 3-pole construction and IEC frame 100 footprint are standard for panel-mounted DIN-rail or screw-fixed installation in industrial switchgear. The nut keeper kit (part of the order code suffix) is a detail for OEMs building DC Power equipment in China — it retains the terminal nuts during vibration, which is a practical concern for transport or high-vibration environments.
