Shop Legrand RX3 MCB 2P 63A Curve C Circuit Breaker | 419703 In Iraq Best Prices

Legrand RX3 2-pole 63A miniature circuit breaker with C-curve protection, 4500A breaking capacity, IP20 fingerproof design, and advanced energy limitation technology for residential and commercial electrical installations.

The Legrand RX3 MCB 2P 63A Curve C is a high-performance miniature circuit breaker designed for residential and small commercial electrical installations. This two-pole circuit breaker features a rated current of 63 amperes with a C-curve tripping characteristic, providing reliable protection against overcurrents and short circuits. With a breaking capacity of 4500A according to IEC 60898-1 standard, this device ensures maximum safety in household electrical systems. The tripping threshold in case of short-circuit is between 315A and 630A (C curve between 5 In and 10 In), offering optimal protection for sensitive electrical circuits. This circuit breaker is engineered with advanced current limiting technology (Class 3 energy limitation) that minimizes let-through energy during fault conditions. The device is protected against solid bodies larger than 12.5mm with IP20 protection rating according to IEC/EN 60529 standard, ensuring fingerproof safety. It can be supplied by either copper cable or prong busbar from the top or bottom, providing flexible installation options. The compact DIN rail mounting design with a width of 34.6mm and depth of 77.3mm makes it ideal for space-constrained electrical panels. Complying with all substance-restriction requirements and designed with environmental consciousness, the Legrand RX3 MCB combines durability with eco-friendly manufacturing. The halogen-free construction ensures safer operation in case of fire. With a rated voltage of 400V AC and impulse withstand voltage of 4kV, this circuit breaker is suitable for both single-phase and three-phase applications in modern electrical installations.
