Breaking capacity across voltage levels
The 3VA1010-2ED36-0AH0: Breaking capacity drops predictably as system voltage rises: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. For a 480 V distribution panel, the 32 kA figure at 415 V is the closest published point — expect a value between 32 kA and 13.6 kA at 480 V, per the standard IEC 60947-2 derating curve for this frame. The 7.5 kA at 690 V confirms suitability for 690 V industrial networks, though the margin narrows at that voltage.
Thermal derating and ambient temperature
The breaker holds its full 100 A rating from 40 °C through 50 °C. Above that, derating is gradual: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. For a panel with internal ambient reaching 55 °C — common in sealed enclosures with multiple heat sources — the continuous current capability is 96 A, not 100 A. The operating temperature range is -25 °C to 70 °C; storage range extends from -40 °C to 80 °C.
Auxiliary contacts and trip indication
This variant includes 2 auxiliary switches plus 1 trip alarm switch (HQ configuration). The trip alarm provides a dedicated signal when the breaker trips on fault — separate from the auxiliary position indication — which simplifies remote fault diagnostics without adding external relays. The breaker has a visible trip indicator on the front face. No undervoltage release, no shunt trip, no communication module, and no ground-fault monitoring are fitted on this order code.
Physical fit and panel integration
Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth. The 76.2 mm width matches the standard 3-pole MCCB footprint for this SENTRON frame — fits existing 3VA base plates and busbar systems without adapter brackets. Front protection is IP40, suitable for enclosed distribution boards where the door provides the environmental seal. The depth of 70 mm leaves clearance for rear-connected busbars in typical 200 mm deep enclosures.
