The Legrand RX³ 6 A MCB is a compact, DIN‑rail mountable thermal-magnetic breaker designed to protect low-rated circuits such as lighting lines, doorbells, intercoms, or alarm systems. It comes in 1-pole, 2-pole, and 3-pole configurations with selectable Curve C (moderate inrush tolerance) or Curve B (tight trip response).
- Curve C (5×–10× In): Trips at roughly 30 A–60 A, suited for lighting and modest inductive loads.
- Curve B (3×–5× In): Trips at approximately 18 A–30 A, ideal for sensitive circuits like doorbells or sensors
- Typical rating: 6 kA at 230 VAC; 10 kA for some variants.
- Meets IEC/EN 60898‑1 and IEC 60947‑2 standards for domestic installations.
- Rated for operation between –25 °C and +70 °C.
