What this breaker does on the line
The Schneider Electric C11E3TM016L is a ComPacT NSXm thermal-magnetic circuit breaker, rated 16 A at 40 °C and breaking 16 kA at 415 V AC. Three poles, Category A utilization, built to EN/IEC 60947-2.
Above 40 °C you derate; the datasheet curve tells you how much. Mechanical durability is 20,000 cycles; electrical durability varies with load: 20,000 cycles at 440 V at half rated current, 10,000 at full rated current. That's typical for a molded-case breaker — it's built for years of routine switching, not just fault protection.
Everlink lugs on the front top and bottom accept 2.5 to 95 mm² rigid copper or aluminum, or 2.5 to 70 mm² flexible copper. Connection pitch is 35 mm with spreaders, 27 mm without. IP40 front face, IK07 impact rating — tough enough for an industrial enclosure door.
