The 10 kA DC breaking capacity at 250 V per IEC 60947-2 is the figure that governs fault clearing; a DC supply with a prospective short-circuit current above that requires an upstream current-limiting device. At 18 mm wide (1 width unit), it occupies a single DIN-rail slot. The 76 mm depth and 70 mm installation depth fit standard distribution boards, but the combined top and bottom terminals accept solid or stranded conductors from 0.75 to 35 mm², so it can handle larger incoming feeds than a typical 16 A MCB. Tightening torque is 2.5 to 3.5 N·m (22–31 lbf·in). The part is sealable and carries IP20 protection with connected conductors, which is standard for enclosed panel mounting. Ambient operating temperature spans -40 to +70 °C, and storage range is -40 to +75 °C — wide enough for unheated railcar vestibules or desert service.
