The Schneider Electric C10F1TM030 is a ComPacT NSX100F circuit breaker, 1-pole, with a TM-D thermal-magnetic trip unit rated 30 A at 40 °C. It breaks 18 kA Icu at 240 V AC (50/60 Hz) per IEC 60947-2, and 36 kA Icu at 250 V DC — that DC rating is unusual for a single-pole frame this size, useful if you are isolating a DC bus in a pitch-control cabinet or brake resistor circuit up-tower.
The 36 kA at 250 V DC is a separate rating — do not assume the same performance at 125 V DC or 48 V DC; consult the coordination tables if you are using it on a battery bank. The TM-D trip unit provides thermal overload protection (L) and magnetic short-circuit protection (I). At 30 A and 40 °C ambient, the thermal element tracks RMS current; below 40 °C it trips slightly slower, above 40 °C you must derate per the IEC 60947-2 thermal curve. The magnetic pickup is fixed at roughly 10× In (300 A), so it will not nuisance-trip on motor inrush unless the motor draws over 300 A locked-rotor.
Mounts on a backplate — not DIN-rail — so plan for screw-down fixing with the 35 mm pole pitch aligning to busbar or cable lugs. The 161 mm height and 86 mm depth fit a standard enclosure, but the 35 mm width per pole means a 1-pole unit occupies one module slot. Front connections top and bottom simplify busbar runs in a distribution board. The IK07 impact rating means it survives a 2 J hammer blow during panel assembly.
