It carries a 150 kA Icu at 415 V AC breaking capacity (code L), making it a high-interrupt choice for distribution switchboards where fault levels run deep. The frame is rated for isolation per EN/IEC 60947-2 and carries a Class II shock protection front face, so it can serve as a visible disconnect in a panel without needing an additional isolator upstream. ## What the ratings mean for a panel build The 630 A continuous rating at 40 °C ambient sets the thermal limit for the bus bars and cable connections on the load side. The 150 kA Icu at 415 V AC means this frame can safely interrupt a fault up to that level without self-destructing — critical for high-fault installations like large motor control centers or transformer secondaries. The Ics (service breaking capacity) at the same voltage is also 150 kA, so after clearing a fault at full rating the breaker can be reclosed and carry load again, not just be swapped out. The 8 kV impulse withstand (Uimp) and overvoltage category III rating confirm it's built for fixed-installation distribution panels, not plug-in equipment. ## Compliance and documentation The C63L4 is certified to EN/IEC 60947-2 and UL 60947-4-1, covering both the circuit breaker standard and the combination motor-controller standard. Pollution degree 3 per IEC 60664-1 means it's rated for industrial environments with conductive pollution. IP40 front face and IK07 impact resistance handle typical panel conditions. The manufacturer provides a declaration of performance and a CE declaration of conformity with the shipment; RoHS and REACH compliance documentation is included in the technical file.","metaTitle":"Schneider Electric C63L4 ComPacT NSX630L Basic Frame, 630A,","metaDescription":"Schneider Electric C63L4 ComPacT NSX630L basic frame, 630 A at 40 °C, 150 kA Icu at 415 V AC.
