What this 3VA1 breaker carries
The Siemens 3VA1132-4GD42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker with a 36 kA breaking capacity at 415 V (class S). It is set for line protection with a TM210 thermal-magnetic trip unit, fixed at 32 A overload protection (Ir = 32 A) and a short-circuit pickup of 10 × In (Ii = 10 × 32 A = 320 A). The N conductor is protected at 100 %.
Where it fits in the panel
This breaker mounts on a DIN rail in a standard distribution or motor-control center enclosure. The 4-pole form factor handles three-phase plus neutral, and the fixed Ir means no field adjustment of the overload threshold — what you order is what you set. The nut keeper kit included with this variant (ZD00 suffix) is specified for DC Power OEM builds in China, so if your BOM calls for that kit, this is the exact code.
