What the ratings mean for fit
The Siemens 3VA1032-2ED36-0KC0 is a SENTRON molded case circuit breaker (MCCB) built for line protection in 3-pole 32 A circuits. The 52.5 kA interrupting rating at 240 V, 32 kA at 415 V, and 7.5 kA at 690 V tell you the fault current it can safely clear at each voltage — critical for selectivity studies and SCCR compliance upstream of a panel. The rated continuous current Iu of 32 A holds across 40 °C to 50 °C, then derates to 28.8 A at 70 °C; that thermal curve governs the actual load you can hang on it in a warm enclosure. Fit: the breaker occupies 130 mm height, 76.2 mm width, 70 mm depth — standard SENTRON 3VA footprint for a 32 A frame. The TM210 thermal-magnetic release handles overloads and short circuits; no undervoltage release, no ground-fault monitoring, no communication module. Two HQ auxiliary switches are factory-fitted (the integrated auxiliary trip is order code 3VA9688-0BL33). Front IP40 means it's protected against tools and wires >1 mm, not against water ingress — keep it inside the enclosure.
