The C11H6TM063B is a Schneider Electric ComPacT NSXm 4-pole thermal-magnetic circuit breaker rated 63 A at 40 °C with a 70 kA breaking capacity at 415 V AC. It's built to EN/IEC 60947-2, so it's certified for distribution duty in industrial panels — isolation suitability is confirmed per that standard. The TM-D trip unit gives you fixed thermal-magnetic protection, no earth-leakage module on this variant. Grey (RAL 7016) housing, 108 mm wide, 12-module pitch on the backplate.
Front terminals accept compression lugs or busbars; neutral is on the left. Connection pitch is 35 mm with spreaders, 27 mm without. IP40 front face, IK07 impact resistance — fine for enclosed panel mounting, not for open washdown zones.
Electrical durability: 20,000 cycles at 440 V at half rated current, 10,000 cycles at full rated current. Mechanical endurance: 20,000 cycles. Relative humidity 0–95 %. Overvoltage category III. Utilisation category A (non-discriminative).
