The Schneider Electric C16BS3FM is a ComPacT NS new generation basic frame — a manually operated 3-pole switch disconnector rated 1600 A continuous (AC-23A) at up to 690 V AC, 50/60 Hz. It is a fixed-mount distribution disconnector with front-front connections on a 70 mm pitch, designed for isolation duty per IEC 60947-3.
The 1600 A AC-23A rating across the full voltage range (220 V to 690 V) means this switch handles motor loads — switching on and off motors, transformers, and other inductive loads — not just resistive heating. The 135 kA making capacity (Icm) at 690 V confirms it can close onto a bolted fault and survive — critical for coordination studies.
Isolation and visibility
This frame is certified for isolation (suitability for isolation Yes per IEC 60947-3). It carries a contact position indicator — green/red flag visible through the front cover — so a technician can verify the gap without opening the door. Note: there is no visible break window; the indicator is the on/off flag, not a gap you can see through.
The C16BS3FM is an active, current-production part (Schneider lists it as Active). No end-of-life notice or last-time-buy is on record.
