Breaking capacity is the headline: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and still 11.9 kA at 690 V. ## Thermal derating — where the 32 A holds and where it doesn't The 32 A rating is continuous at ambient up to 50 °C. Above that, the thermal-magnetic release starts to pull back: 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. For a 32 A continuous load at 65 °C ambient, you'd need to step up to a 35 A frame or ventilate the enclosure. The derating curve is built into the TM210; no field adjustment. ## Undervoltage release and integration That's useful for safety circuits, emergency-stop chains, or any scheme where a loss of control voltage must kill the load. The UVR's own order code is 3VA9608-0BB24, which is the spare part if the release fails. No auxiliary contacts are included (auxiliary contact version: without), so if you need status feedback to a PLC, you'll add a separate auxiliary switch block. Mounting is the standard SENTRON 3VA footprint: 70 mm deep, 76.2 mm wide (3-pole), 130 mm tall. Panel cutout and screw-terminal layout match the rest of the 3VA line, so swapping between 32 A and 63 A frames in the same enclosure position is straightforward.","metaTitle":"Siemens 3VA1032-4ED32-0CA0 SENTRON MCCB, 32 A, 3-Pole, TM210","metaDescription":"Siemens SENTRON 3VA1032-4ED32-0CA0 molded case circuit breaker, 32 A rated, 3-pole, TM210 release.
