Legrand RX3 4-pole miniature circuit breaker with 16A rated current, 6000A breaking capacity, and C-curve protection for household and commercial electrical installations
The Legrand RX3 MCB (Miniature Circuit Breaker) is a 4-pole circuit breaker designed for household and small commercial electrical installations. With a rated current of 16A and a breaking capacity of 6000A according to IEC 60898-1 standard, this device provides reliable protection against overcurrent and short-circuit faults. The C-curve characteristic offers a tripping threshold between 80A and 160A (5 to 10 times the rated current), making it ideal for circuits with moderate inrush currents such as general lighting and socket outlets.
This circuit breaker features advanced energy limitation technology (Class 3 according to IEC 60898-1), which significantly reduces let-through energy during fault conditions, protecting downstream equipment from damage. The device is rated at 400V AC with an impulse withstand voltage of 4kV, ensuring excellent protection against transient overvoltages. It offers flexible installation options with supply via copper cable, prong busbar (top or bottom), or fork busbar (bottom side), making it adaptable to various switchboard configurations.
Designed with safety and environmental consciousness in mind, the RX3 MCB is IP20 rated (fingerproof protection against solid bodies larger than 12.5mm) and complies with substance-restriction requirements. The device measures 70.8mm in width, occupying 4 modular spacings on standard DIN rails, and features terminal marking for easy identification. All protective functions operate on all four poles with concurrent switching of the neutral conductor, ensuring comprehensive circuit protection. This product represents Legrand's commitment to reliable, efficient electrical safety solutions for modern installations.
