Single-pole 32A miniature circuit breaker with 6000A breaking capacity, curve C characteristic, IP20 protection, and class 3 current limiting for reliable household and commercial electrical protection.
The Legrand RX3 MCB (Miniature Circuit Breaker) 1 pole 32A with curve C characteristic is a high-performance electrical protection device designed for household and small commercial installations. This single-pole circuit breaker features a breaking capacity of 6000A according to IEC 60898-1 standard, providing reliable protection against overloads and short circuits. With a tripping threshold between 160A and 320A (C curve between 5 In and 10 In), it offers optimal protection for sensitive circuits requiring moderate time delay. The device is IP20 rated (fingerproof protection against solid bodies larger than 12.5mm) and achieves maximum energy limitation with class 3 current limiting capability.
The RX3 circuit breaker can be supplied through multiple connection methods including copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), providing flexible installation options. With a rated voltage of 230V AC and insulation voltage of 500V, this device is suitable for standard residential electrical networks. The compact design features a width of 17.7mm (1 modular spacing), height of 88.5mm, and depth of 77.8mm, allowing for efficient use of DIN rail space in distribution panels. The grey colored housing (RAL 7035) complies with environmental standards and substance-restriction requirements.
This product is engineered for reliability and safety, featuring terminal marking indication for easy identification and screwed terminal connections. The RX3 operates at frequencies between 50-60Hz and maintains performance across nominal voltages of 210-250V. Installation should be performed by qualified electricians in compliance with local electrical codes. The device includes comprehensive documentation and certifications including VDE and CB agreements, ensuring compliance with international safety standards.
