The Legrand RX³ 16 A MCB is a thermal-magnetic miniature circuit breaker designed to protect electrical circuits from overloads and short-circuits. It’s available in single-pole (1P), 2-pole (2P), and 3-pole (3P) configurations, with Contour C or B tripping curves optimized for different inrush and load conditions.
- Curve C (5×–10× In): Suited for circuits with moderate inrush (e.g. motors, LED lighting)
- Up to 6 kA at 230 VAC for most 1P/2P/3P Curve C variants
- Curve B also rated at 6 kA per IEC and EN standards
- Width varies by poles: 1 module (~18 mm) for 1P, 2–3 modules for 2P/3P
- Operates reliably between –25 °C and +70 °C
