Shop Legrand RX3 MCB 3 Pole 10A Curve B Circuit Breaker | 419167 In Iraq Best Prices
Legrand RX3 3-pole MCB with 10A rated current and B-curve characteristic, 6000A breaking capacity, IP20 protection, ideal for residential and small commercial electrical installations with reliable overload and short-circuit protection.
The Legrand RX3 MCB (Miniature Circuit Breaker) is a high-performance 3-pole circuit breaker designed for residential and small commercial electrical installations. With a rated current of 10A and a breaking capacity of 6000A at 400V, this device provides reliable protection against overloads and short circuits. The B-curve characteristic offers optimal tripping between 3 to 5 times the rated current, making it ideal for general-purpose applications with moderate inrush currents. This modular breaker features a 44mm built-in depth and is designed for DIN rail mounting, allowing for space-efficient installation in electrical panels. The product complies with IEC 60898-1 standards and offers IP20 protection rating, ensuring fingerproof operation and safety in compliance with international electrical standards.
The RX3 series is engineered with advanced current limiting technology (Class 3), which significantly reduces let-through energy during fault conditions, providing superior protection for connected equipment. The device can be supplied via copper cable, prong busbar, or fork busbar connections, offering flexible installation options for various panel configurations. With a rated voltage of 400V and impulse withstand voltage of 4kV, this circuit breaker ensures safe operation in demanding electrical environments. The grey color (RAL 7035) and professional design make it suitable for modern electrical installations. All Legrand products must be installed and maintained exclusively by trained and approved personnel to ensure optimal performance and safety.
This circuit breaker is an essential component for electrical safety in residential and small commercial applications. It provides automatic disconnection in case of overcurrent or short-circuit conditions, protecting both personnel and equipment from electrical hazards. The RX3 MCB represents Legrand's commitment to quality, reliability, and compliance with environmental and safety regulations. Proper installation according to local electrical codes and manufacturer instructions is essential for safe operation.
