The Legrand DX³ 10 A MCB is a modular, DIN-rail mounted thermal‑magnetic circuit breaker designed to protect circuits against overloads and short-circuits. Available in configurations ranging from single-pole (1P) to four-pole (4P), it offers selectable tripping curves (B, C, or D) suited for specific load profiles. Ideal for residential and light industrial installations.
- Available in Curve C (trips between 50 A–100 A) and Curve D (trips between 100 A–140 A).
- Icu up to 32 kA at 230 VAC and ~16 kA at 400 VAC (depending on curve and pole count)
- Rated voltage support up to 400 VA
- Operates reliably from –25 °C to +70 °C
