What this MCCB delivers on the line side
The Siemens SENTRON 3VA1032-2ED36-0JC0 is a 3-pole molded case circuit breaker rated for 32 A continuous current (Iu) with a TM210 thermal-magnetic release. Its interrupting capacity hits 52.5 kA at 240 V and 32 kA at 415 V — enough to clear high-fault scenarios on distribution or feeder circuits without cascading upstream. The shunt trip (STL) auxiliary release lets a remote signal or safety relay force the breaker open, which is useful for emergency-stop circuits or undervoltage protection schemes where you need a controlled trip independent of the overcurrent element. Rated insulation voltage is 800 V (Ui), and the breaker carries two HQ auxiliary switches for status feedback to a PLC or annunciator panel. The front face is IP40-rated, so it's fine inside a clean enclosure but not for washdown areas. No trip indicator on the front — you'll rely on the auxiliary contacts or a remote I/O point to confirm state.
Thermal derating and ambient limits
The 32 A rating holds flat from 40 °C through 50 °C. Above that, it derates stepwise: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. If your panel ambient runs hot — say, near a drive cabinet or in a non-conditioned electrical room — size the load to the derated figure, not the nameplate 32 A. Operating range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
Panel fit and integration notes
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep. It mounts on a DIN rail or directly to a backplate via the screw terminals. The 3-pole footprint matches the standard SENTRON 3VA frame, so if you're swapping from a 3VA1010 or 3VA1020 variant, the mounting holes and busbar spacing are identical — no rewiring of the buswork needed. The shunt trip coil (STL) is wired separately; verify polarity on the auxiliary release per the terminal diagram.
