Breaking capacity runs 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V, which covers most industrial distribution panels up to 690 V line-to-line. This is a line-protection variant — no ground-fault monitoring, no phase-failure detection, no communication module, and no auxiliary contacts. The only integrated auxiliary release is a shunt trip (STL) with order code 3VA9688-0BL30. If your BOM calls for under-voltage release or an alarm contact, this isn't the variant.
Thermal derating matters above 55 °C
At 55 °C it derates to 38.4 A, at 60 °C to 37.6 A, at 65 °C to 36.8 A, and at 70 °C to 36 A. Size the breaker for the actual enclosure temperature, not the nameplate.
No trip indicator, no aux contacts — plan your panel wiring
This MCCB lacks a trip indicator and has no auxiliary contact block. If the PLC needs a remote tripped signal, you'll need to add an external auxiliary switch or monitor the shunt trip circuit. Dimensions: 130 mm height, 76.2 mm width, 70 mm depth — fits standard SENTRON 3VA mounting footprint.
