The Siemens 3VA1132-6GD42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker with a 70 kA breaking capacity at 415 V (class H). It's configured for line protection with a TM210 thermal-magnetic trip unit, fixed at 32 A overload protection (Ir) and a short-circuit pickup (Ii) set at 10 x In. The N conductor is protected at 100%, and it includes a nut keeper kit — a detail that matters if you're panel-building in a DC Power OEM environment in China, where that kit keeps the mounting hardware from walking loose during transit or vibration.
The 70 kA Icu at 415 V puts this in breaking capacity class H — it's sized for high-fault installations where the available short-circuit current is substantial. The fixed Ir (32 A) and fixed Ii (10 x In) mean no field-adjustable dials; the trip curve is locked at the factory. That simplifies ordering if the design is frozen, but it also means you need to confirm the 32 A setting matches your load before you commit the line item.
