The Legrand DX³ 6 A MCB is a thermal‑magnetic miniature circuit breaker available in multiple configurations: single-pole (1P), 2-pole (2P), or 3-pole (3P), with tripping curves B, C, or D. Rated at 6 A, it’s tailored for low-current circuits in residential or light industrial installations
- Available in Curve C (trips at ~30–60 A / 5×–10× In) for moderate inrush loads, and Curve D (10×–14× In) for higher inrush scenarios.
- Curve C/D models in multi‑pole configurations support up to 25 kA at 230 VAC, or 10 kA at 400 VAC.
- Compact DIN‑rail mounting: single‑pole occupies 1 module (~18 mm), while 2P/3P variants use 2–3 modules.
