The Schneider Electric C10F4TM016C is a ComPacT NSX100F moulded-case circuit breaker (MCCB) with a 16 A thermal-magnetic TM-D trip unit, 4 poles, and an F breaking capacity code — 36 kA Icu at 415 V AC. It is designed for distribution applications per EN/IEC 60947-2, with suitability for isolation (yes, per that standard). The 16 A rating at 50 °C means this is the continuous current it handles without nuisance tripping in a warm panel; the thermal element protects against overload (L), the magnetic element against short-circuit (I). For selectivity coordination downstream, that figure gives you headroom to size upstream breakers. At 220/240 V AC the interrupting rating jumps to 85 kA Icu, so it handles high-fault locations like a step-down transformer secondary.
The 4-pole configuration has the neutral on the left (fixed position). Front connections both top and bottom, with a 35 mm connection pitch.
