Its 187 kA interrupting capacity at 240 V gives substantial fault-clearing headroom for high-fault installations, while the 121 kA at 415 V and 75.6 kA at 440 V cover common industrial voltage levels.
Current rating holds at 160 A from 40 °C through 50 °C, then derates to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. The 70 mm depth and 101.6 mm width fit standard panel cutouts for 4-pole MCCBs; the 130 mm height is compact for a 160 A frame. Mounting is via screw-clamp or optional DIN-rail adapter (not included), typical for SENTRON 3VA series integration into switchboards or sub-distribution boards.
