Shop Legrand RX3 MCB 1 Pole 25A Curve B Circuit Breaker | 419138 In Iraq Best Prices
Single-pole 25A miniature circuit breaker with B-curve characteristic, 6000A breaking capacity, IP20 protection, and advanced current-limiting technology for reliable household and commercial electrical protection.
The Legrand RX3 MCB (Miniature Circuit Breaker) is a single-pole, 25A rated circuit breaker with B-curve tripping characteristic, designed for household and small commercial electrical installations. This device features a breaking capacity of 6000A according to IEC 60898-1 standard, providing reliable protection against overcurrent and short-circuit conditions. The B-curve characteristic offers a tripping threshold between 75A and 125A (3-5 times the rated current), making it ideal for general-purpose applications with moderate inrush currents.
The RX3 breaker is engineered with advanced current-limiting technology (Class 3 energy limitation) to minimize let-through energy during fault conditions, ensuring maximum protection for connected equipment. The device is rated for 230V AC operation with a frequency range of 50-60Hz and an impulse withstand voltage of 4kV. It features IP20 protection rating (fingerproof against solid bodies larger than 12.5mm) and can be supplied via copper cable, prong busbar, or fork busbar connections for flexible installation options.
Built with environmental consciousness and compliance to substance-restriction requirements, this Legrand circuit breaker is suitable for DIN rail mounting in residential panels and small commercial switchboards. The grey-colored device (RAL 7035) measures 17.7mm in width and is designed for easy installation and maintenance by qualified electricians. All Legrand accessories should be used for optimal performance and warranty compliance.
