Schneider Electric M9U21210 Miniature Circuit Breaker

Schneider Electric M9U21210 Miniature Circuit Breaker is a 2-pole device from the Multi9 C60H-DC family, rated for 10 A with a C‑curve trip characteristic. It supports DC service up to 500 V DC and provides protective interrupting capacity of 5 kA under UL 1077 and 6 kA under IEC/EN 60947-2; regional listings also show 10 kA at 500 V DC. This compact, plug‑in MCB disconnects both poles simultaneously to protect wiring and downstream equipment in DC power distributions and control panels. As part of Schneider Electric’s Multi9 line, the M9U21210 is designed for easy panel mounting with a 9 mm per-pole module width and compatibility with common Multi9 accessories for remote indication and tripping. The 2P, 10 A, C-curve configuration makes it suitable for general DC protection in industrial installations where reliable, predictable trip behavior is required.
