## Summary description

The Legrand 411800 DX3 is a 4-pole residual current circuit breaker designed for electrical safety. It features a 40A rated current and 0.3A sensitivity, classified as Type A-S for selective protection. This device is essential for preventing electrical faults and ensuring circuit protection in residential and commercial installations. Its robust design ensures reliable performance in demanding electrical systems.

## Long description

The Legrand 411800 DX3 is a high-performance 4-pole residual current circuit breaker (RCCB) engineered to provide superior electrical safety in both residential and commercial environments. This device is specifically designed to detect both AC and pulsating DC residual currents, ensuring comprehensive protection against electrical faults. As a Type A-S selective device, it offers enhanced immunity to unwanted tripping, making it an ideal solution for complex electrical installations where reliability and stability are paramount.
Advantages
This circuit breaker stands out due to its robust construction and advanced technical capabilities. By utilizing Type A-S technology, the device provides selective protection, which helps in coordinating with downstream protective devices to prevent unnecessary power outages. Its ability to detect both AC and DC component faults ensures a higher level of safety compared to standard AC-type breakers. Furthermore, the unit is designed for durability and can be easily integrated with various DX3 auxiliaries and accessories to expand its functionality according to specific system requirements.
Suitable for
Residential electrical distribution boards
Commercial and industrial power systems
Installations requiring selective protection to prevent nuisance tripping
Circuits where electronic equipment may introduce DC components into the electrical network
This device may not be suitable for applications requiring standard instantaneous tripping, as the selective (S) characteristic introduces a deliberate time delay. It is also not intended for use in circuits exceeding its rated current of 40A or in environments where the specific fault current sensitivity of 0.3A is not appropriate for the required level of human or equipment protection.
Key specifications
Number of poles: 4
Rated current: 40A
Residual current sensitivity: 0.3A
Type: A-S (Selective)
Compliance: IEC 61008-1
Colour: Grey
Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is mounted on a standard DIN rail within a distribution board. Ensure that the supply voltage and load characteristics are compatible with the breaker specifications before connection. Once installed, the device should be tested periodically using the integrated test button to verify its operational integrity.
What to consider before purchase
Verify that the 40A rated current matches your circuit load requirements
Confirm that the 0.3A sensitivity meets the safety standards for your specific application
Ensure compatibility with existing DX3 series accessories if expansion is planned
Check that the selective (S) time-delay characteristic is appropriate for your circuit coordination needs
Usage recommendations: Regularly perform a functional test using the test button at least every six months to ensure the mechanism remains responsive and the protection remains active.
