At 415 V it still holds 75.6 kA, and at 690 V it's 11.9 kA, so it covers low-voltage distribution up through 690 V line-to-line. Rated continuous current is 20 A across the ambient range from 40 °C to 55 °C; above that it derates to 19 A at 60–70 °C. That's enough for remote status monitoring and a safety undervoltage trip without adding external relays. The UVR is what makes this a fit for emergency-stop chains or generator-transfer schemes where loss of control voltage must drop the load.
Sizing and selectivity reality
For a 20 A MCCB in a typical distribution board, it's manageable, but it's not a number to ignore in a sealed stainless-steel cabinet. Compared to the 3VA1110-5ED36-0AC0, which is a 16 A frame with different trip characteristics, this 20 A unit keeps the same 3-pole footprint and the same SENTRON platform. If you're replacing a 16 A MCCB in an existing panel, the 20 A version will bolt into the same bus bars and mounting holes — no rewiring needed — provided the upstream protection and cable sizing allow the higher rating. The auxiliary switch count and UVR fit are identical, so the control wiring carries over unchanged.
Panel fit and environmental range
Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — a standard 3-pole MCCB footprint that drops into SENTRON distribution boards and most third-party panelboards with bus-bar centers at 60 mm. No derating for altitude is listed, but the 800 V insulation rating gives headroom for high-altitude installations.
