The Siemens 3VA1132-4ED32-0AA0-ZD00 is a 3-pole IEC frame 160 circuit breaker in the 3VA1 series, rated at 32 A with a breaking capacity class S delivering Icu=36kA at 415 V. It carries TM210 line protection with fixed overload protection Ir=32A and fixed short-circuit protection Ii=10 x In. The FTFM (Fixed Thermal Fixed Magnetic) trip unit means no field-adjustable magnetic pickup — what you see on the nameplate is what you get for coordination studies. This variant includes a nut keeper kit and is built for DC Power OEM applications in China.
What the ratings mean for fit
The 36 kA Icu at 415 V places this breaker in breaking capacity class S — it safely interrupts a fault current up to that level without welding contacts or cascading failure upstream. For a 32 A line protection breaker on a 415 V three-phase supply, that headroom covers most industrial secondary distribution panels. The fixed Ir=32 A means the thermal overload is set at the factory; no dial to turn, which simplifies procurement but demands the load be exactly 32 A or lower. The fixed Ii=10 x In (320 A magnetic trip) is typical for motor-starting inrush on smaller loads, but verify against your specific load's locked-rotor current if you're feeding a motor starter.
Deployment context
This breaker mounts on a DIN rail inside a standard 160 A frame footprint — the 3VA1 series uses the same panel cutout as the legacy 3VL1, so a retrofit into an existing Siemens panel is straightforward. The nut keeper kit (included) secures the busbar connection on the line side; don't skip it if you're running copper busbars instead of cable tails.
