The Siemens SENTRON 3VA1032-4ED36-0KA0 is a 3-pole molded case circuit breaker rated for 32 A continuous current and a 121 kA interrupting capacity at 240 V. It carries a TM210 thermal-magnetic overcurrent release and a factory-integrated shunt trip (STL) — no auxiliary contacts or undervoltage release on this variant. The interrupting ratings step down to 75.6 kA at 415 V and 52.5 kA at 440 V, with 11.9 kA remaining at 690 V, so it handles high-fault service-entrance or distribution panels where the available fault current is substantial.
Thermal derating and enclosure fit
The breaker holds its full 32 A rating up to 50 °C ambient; above that it derates linearly to 28.8 A at 70 °C. In a sealed panel with minimal airflow, that derating curve governs the real load you can protect. The 70 mm depth and 76.2 mm width fit standard SENTRON 3VA panel cutouts, and the IP40 front protection keeps dust out of the enclosure face.
