The C11F44V100L is a Schneider Electric ComPacT NSXm moulded-case circuit breaker (MCCB) rated 100 A at 40 °C with a 36 kA breaking capacity at 415 V AC — that interrupting rating tells you it can clear a fault up to 36 kA without welding contacts or rupturing the case, which is the deciding number for panel coordination studies under EN/IEC 60947-2. The 4P (four-pole) construction with the neutral on the left covers three-phase plus neutral distribution applications where you need to switch and protect all four conductors.
Deployment context
The Everlink lugs accept 2.5 to 95 mm² rigid or stranded copper or aluminium on the line side, 2.5 to 70 mm² fine-stranded copper on the load side, so you can land the feeder and downstream conductors without adapters. IP40 enclosure protection means it is suited for indoor panel installation where dust ingress is controlled; the IK07 impact rating handles incidental tool contact during maintenance.
