The Siemens SENTRON 3VA1010-3ED32-0KH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current Iu of 100 A and an interrupting capacity of 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V. It is fitted with a TM210 thermal-magnetic overcurrent release and a shunt trip (STL) auxiliary release. The front face is IP40 rated, suitable for panel-mount applications where the breaker is protected within an enclosure.
Ratings and what they mean for your panel
The 100 A continuous current rating holds flat from 40 °C to 50 °C, then derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. For a panel running at 50 °C ambient, you get the full 100 A; above that, the derating curve governs the real load capacity. The interrupting ratings span from 75.6 kA at 240 V down to 7.5 kA at 690 V — the 415 V figure of 52.5 kA is the one most relevant for standard European 400 V distribution, confirming it clears high-fault scenarios without upstream coordination issues.
Integration and auxiliary fit
The breaker ships with 2 auxiliary switches plus 1 trip alarm switch (HQ configuration) installed. The shunt trip release (STL) is factory-fitted; the integrated auxiliary trip order code is 3VA9688-0BL33. No undervoltage release, no communication module, no phase failure detection — this is a straightforward line-protection MCCB with remote trip capability via the shunt trip. Panel cutout dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall, fitting standard SENTRON 3VA mounting footprints.
