The C10F4D is a Schneider Electric ComPacT NSX DC basic frame, designated NSX100F DC, rated 100 A at 40 °C with a 36 kA breaking capacity at 750 V DC across three poles. It is a 4-pole fixed-mount frame without a trip unit, intended for DC distribution applications per IEC 60947-2.
Breaking capacity and DC ratings
The 36 kA Icu holds across the full DC voltage range: 250 V DC single-pole, 500 V DC two-pole, and 750 V DC three-pole. The Ics (service breaking capacity) matches the Icu at each voltage, meaning the breaker can be reclosed after a fault at full rated current without derating — a key spec for DC bus protection where fault currents are sustained. Rated operational voltage is 750 V DC, with insulation voltage also 750 V DC.
Physical integration and mounting
Fixed backplate mounting, 140 mm wide by 161 mm high by 86 mm deep. IP40 front face, IK07 impact resistance — standard for enclosed distribution boards.
Listed as current production. This is a basic frame — no trip unit included — so the buyer must pair it with a compatible electronic or thermal-magnetic trip unit (e.g., Schneider Micrologic series) to complete the breaker.
