The C11F4TM100B is a Schneider Electric ComPacT NSXm 4-pole moulded-case circuit breaker with a 100 A thermal-magnetic TM-D trip unit, rated 36 kA at 415 V AC (performance level F). The thermal-magnetic TM-D trip provides inverse-time overload protection (thermal element) and instantaneous short-circuit protection (magnetic element), so it covers both sustained overloads and hard faults in one device. Rated 100 A at 40 °C, it's sized for 100 A feeder or branch circuits in 50/60 Hz AC networks.
Mounts on a backplate in horizontal or vertical orientation — flat against the panel. The 108 mm width (12 module pitches at 9 mm) and 137 mm height fit standard DIN-rail enclosures; depth is 80 mm. Connection terminals accept compression lugs or busbars, with front-facing upside and downside connections for straightforward panel wiring. Neutral is on the left. Pollution degree 3 (IEC 60664-1) means it's rated for conductive pollution environments typical in industrial control panels — no derating needed for the usual factory-floor dust and humidity (0–95 % RH).
Suitability for isolation is confirmed per that standard — so it can be used as a disconnecting means in the panel. IP40 front face (IK07 impact resistance) keeps dust and accidental tool contact out; not rated for washdown, so keep it in a dry enclosure. Overvoltage category III, suitable for fixed-installation distribution boards.
