Legrand 419229 MCB RX³ 2P 50A Curve C 6kA DIN Rail

The Legrand 419229 is an RX³ miniature circuit breaker (MCB), 2-pole, rated 50 A on the C tripping curve, for 400 V installations. It has a short-circuit breaking capacity of 6 kA per IEC 60898-1, occupies 2 modules on a DIN rail, and provides overcurrent and short-circuit protection for residential and small-commercial distribution circuits.

Features and benefits:

• Thermal-magnetic tripping provides reliable protection against overloads and short circuits.
• Class 3 energy limitation per IEC 60898-1 minimises let-through energy during a fault.
• Accepts copper cable, prong busbar, or fork busbar for flexible distribution-board assembly.
• Compact 1-module-per-pole footprint suits dense modular enclosures.

Applications:

• Final circuit protection for residential and small-commercial distribution boards up to 50 A.
• Lighting, socket-outlet and small-appliance feeders requiring C-curve tripping behaviour.
• Series coordination with upstream RCDs in TT and TN-S supply systems.
• Modular distribution enclosures conforming to IEC 60898-1.
