Shop Legrand RX3 MCB 1 Pole 50A Curve B Circuit Breaker | 419141 In Iraq Best Prices
Legrand RX3 single-pole 50A miniature circuit breaker with 6000A breaking capacity, B-curve characteristic, IP20 protection, and DIN rail mounting for residential electrical installations.
The Legrand RX3 MCB (Miniature Circuit Breaker) is a single-pole 50A circuit breaker designed for residential and small commercial electrical installations. This device features a breaking capacity of 6000A according to IEC 60898-1 standard, providing excellent protection for household electrical systems. The B-curve characteristic offers a tripping threshold between 150A and 250A (3-5 times the rated current), making it ideal for circuits with moderate inrush currents. The breaker is fingerproof with IP20 protection rating, ensuring safety in domestic environments.
This MCB can be supplied with copper cable, prong busbar (top or bottom side), or fork busbar (bottom side) connections, offering flexible installation options. The device features current limiting class 3, providing maximum energy limitation according to IEC 60898-1 standard. With a rated voltage of 230V AC and impulse withstand voltage of 4kV, this breaker ensures reliable performance across standard residential electrical networks. The compact design with 17.7mm width fits standard DIN rail installations, making it suitable for modern electrical panels.
The Legrand RX3 is manufactured with environmental consciousness and complies with substance-restriction requirements. It operates reliably at frequencies between 50-60Hz and maintains performance across storage temperatures from -40°C to +70°C. The device includes terminal marking indication for easy identification and features a grey color (RAL 7035) for standard panel aesthetics. Professional installation by qualified electricians is recommended to ensure optimal safety and compliance with local electrical codes.
