Residual Current Device RX3 4P 40A 30mA TYPE AC 402063

RX3 residual current circuit breaker – reliable installation protection

The RX3 4P 40A 30mA Type AC residual current circuit breaker is a key element ensuring safety in every electrical installation. The device effectively protects against electric shock and prevents damage resulting from short circuits. It is a proposal from a renowned manufacturer, Legrand, valued for its high quality and innovative solutions.

This circuit breaker finds application in both home and industrial installations where high reliability and protection of people and equipment are required. Its versatility makes it an ideal choice for both professional installers and end users. DIN TH35 rail mounting simplifies integration with existing electrical infrastructure.

Features and benefits

• High protection efficiency: Rated residual current of 30mA ensures rapid circuit disconnection in the event of a leakage current, minimizing the risk of electric shock.
• Versatile application: Type AC ensures that the circuit breaker effectively reacts to alternating leakage currents, typical of most electrical appliances.
• Solid construction: Short-circuit strength at 10kA guarantees stable operation even in the event of overloads.
• Easy installation: Mounting on a standard DIN TH35 rail allows for quick and trouble-free installation.
• Safe operation: With a lock preventing accidental switching on after switching off due to a failure.
• Wide range of wires: The ability to connect wires with a cross-section from 0.75 mm² to 50 mm² (solid) and from 0.75 mm² to 35 mm² (stranded) ensures compatibility with various types of cabling.
• High manufacturing quality: Legrand products are characterized by durability and reliability, which translates into long-term and safe use.
• Compliance with standards: Meets the requirements of EN 61008-1 standard, confirming its safety and quality.

Technical parameters and application

The RX3 circuit breaker has four poles (4P) and is designed to operate at a rated voltage of 400V and a frequency of 50Hz. Its width is 4 modules (71.2 mm), which allows for efficient use of space in the switchgear cabinet. The ambient temperature in operating conditions is in the range of -25°C to +60°C, which ensures its reliability in various environmental conditions. The degree of protection IP20 means protection against touching with a finger and solid objects larger than 12.5 mm – the device is intended for use indoors. The rated impulse withstand voltage Uimp is 4kV, which ensures resistance to transient overvoltages occurring in the electrical network.
