MCCB for high-fault line protection
Rated insulation voltage 800 V, with breaking capacities that step down from 187 kA at 240 V to 121 kA at 415/440 V, then 75.6 kA at 500 V and 52.5 kA at 690 V.
Current derating and thermal budget
At 55 °C it derates to 960 A, at 60 °C to 940 A, at 65 °C to 920 A, and at 70 °C to 900 A. Maximum power loss is 330 W; the enclosure ventilation must clear that heat to avoid compounding the ambient rise.
Dimensions: 320 mm height, 210 mm width, 120 mm depth. The 210 mm width is the three-pole frame — verify the mounting footprint against the existing backpanel cutout or DIN-rail adapter if retrofitting into an older SENTRON or 3VA panel. No communication function on this variant; it's a standalone thermal-magnetic or electronic-trip breaker with shunt trip control wiring only.
