What this breaker carries and where it fits
The Siemens 3VA1196-4GD42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker with a 16 A thermal-magnetic trip unit (TM210). Its 36 kA breaking capacity at 415 V (class S) means it safely clears high fault currents on a 400 V line — enough for most industrial distribution panels downstream of a transformer. The fixed Ir=16 A overload and Ii=20 x In short-circuit setting (320 A magnetic pickup) are set at the factory, so there's no field-adjustment dial; you order the exact rating your BOM calls for.
Lifecycle and sourcing reality
Availability and current pricing are confirmed at quote time against an RFQ through independent distribution. The nut keeper kit and DC Power OEM designation in the description indicate this variant was built for a specific OEM build; verify the accessory kit matches your panel hardware before committing the order.
What the ratings mean for your panel
The 36 kA Icu at 415 V is the breaker's ultimate breaking capacity — it can interrupt a fault up to that level once and still be functional afterward. For selectivity studies, pair it with upstream breakers rated at least one class higher (e.g., class L or H) so the downstream device clears first. The 100% N conductor protection means the neutral pole is rated for full phase current, not a reduced cross-section — important on 4-wire systems with harmonic loads. Mounts in a standard Siemens 3VA1 panelboard or individual enclosure. The nut keeper kit is a captive-hardware detail that saves time on the gland plate — no loose washers to drop inside the panel. The DC Power OEM suffix suggests this unit was originally kitted for a DC-side application in China; confirm the DC voltage rating if reusing outside that scope.
