The C250S3FM is a ComPacT NS new generation basic frame — a 3-pole, fixed-mount switch disconnector rated for 2500 A in AC-23A duty across 220–690 V AC. That AC-23A rating covers motor loads and mixed resistive-inductive switching, so it handles high-inrush loads like transformers or large motors without derating.
Fixed-mount footprint: 420 mm high, 350 mm wide, 160 mm deep. Connection pitch is 70 mm, with both upside and downside connections on the front — good for panel layouts where rear access is tight. IP40 enclosure protection keeps out tools and fingers but not water; install in a dry cabinet or add a cover for washdown areas. Storage temperature range is -50 to 85 °C, operating is -25 to 70 °C. Mechanical endurance is 6000 cycles, electrical endurance 1000 cycles at 440 V — typical for a high-current disconnect that sees infrequent manual operation. IK07 impact rating means it survives a 2 J hammer blow to the enclosure face.
Network frequency is 50/60 Hz, so it's at home on either 50 Hz or 60 Hz distribution without a different variant. Standards base is IEC 60947-3; no UL or CSA listing appears on this record, so verify local code acceptance if the job requires it.
