The Schneider Electric C250H4FM is a basic frame from the ComPacT NS1600b...3200 new generation range, rated 2500 A at 50 °C. It is a 4-pole, fixed-mount, manually operated frame without an integral trip unit — you add the protection module separately. The breaking capacity is 85 kA Icu at 415 V AC (125 kA at 240 V), certified to IEC 60947-2, which means it can safely interrupt fault currents up to that level in a distribution panel without upstream cascading.
Rated current of 2500 A at 50 °C sets the continuous load limit in a typical 50 °C enclosure ambient; above that temperature you derate per the manufacturer's curve. Short-time withstand (Icw) is 32 kA for 3 seconds, which matters for selective coordination: downstream breakers can clear a fault while this frame holds closed long enough to maintain supply to healthy feeders. Overvoltage category III suits fixed-installation distribution boards. The IP40 front face and IK07 impact resistance handle accidental tool contact and minor knocks during panel assembly.
Dimensions are 535 mm wide × 330 mm high × 160 mm deep, with a connection pitch of 115 mm. Neutral is on the left. The manually operated control type means no motor operator or remote closing mechanism is included; add those as accessories if needed. Power losses are 100 W at rated current, so factor that into enclosure ventilation.
