Single-pole 20A Legrand RX3 circuit breaker with Curve C characteristic, 6000A breaking capacity, ideal for residential and small commercial applications with advanced current limiting and DIN rail mounting.
The Legrand RX3 MCB (Miniature Circuit Breaker) is a single-pole 20A circuit breaker with Curve C tripping characteristic, designed for residential and small commercial electrical installations. This device offers a breaking capacity of 6000A according to IEC 60898-1 standard, providing reliable protection for household circuits against overloads and short-circuits. The breaker features a tripping threshold between 100A and 200A (C curve between 5In and 10In), making it suitable for general-purpose applications including lighting circuits and standard power distribution.
The RX3 circuit 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 supply at 50-60Hz frequency and offers an impulse withstand voltage of 4kV. It can be supplied via copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), providing flexible installation options. The breaker complies with IP20 protection rating against solid bodies larger than 12.5mm, ensuring safety and preventing accidental contact with live components.
With its compact DIN rail mounting design (17.7mm width, 1 modular spacing), the RX3 integrates seamlessly into standard electrical panels and distribution boards. The product features terminal marking indication for easy identification and maintenance. Built to stringent environmental standards, this Legrand circuit breaker is halogen-free and complies with RoHS and REACH regulations. It operates reliably across a storage temperature range of -40°C to +70°C and maintains consistent performance in pollution degree 2 environments.
