C10N4TM063C — ComPacT NSX 63 A, 4P, TM-D, 50 kA
The Schneider Electric C10N4TM063C is a ComPacT NSX100N circuit breaker, 4-pole, rated 63 A at 50 °C with a TM-D thermal-magnetic trip unit.
At 220/240 V AC the Icu jumps to 90 kA; at 690 V AC it drops to 10 kA. For a 415 V distribution board, the 50 kA figure sets the upstream fault level the breaker must clear — coordinate with a higher-rated upstream device if the prospective short-circuit current exceeds that. The 63 A continuous rating and the TM-D curve give you the LSI protection band for a feeder or a large submain.
The 140 mm width and 86 mm depth fit standard distribution panel layouts; the 35 mm connection pitch matches common busbar and terminal-block spacing. IP40 enclosure protection and IK07 impact resistance suit indoor distribution boards in clean industrial or commercial environments.
Durability and neutral protection
Mechanical durability rated at 50,000 cycles; electrical durability varies with load — 50,000 cycles at 440 V at half rated current, 30,000 at full rated current, and 10,000 at 690 V at full rated current. The 4-pole version (4D) provides neutral protection at 1 x Ir — fully rated neutral pole, not a switched-only neutral. Neutral position is left. No integrated earth-leakage protection; add a Vigi module if ground-fault detection is required.
