## Long description

The Legrand 411972 circuit breaker DX3 residual current device is engineered to provide reliable electrical protection and safety for both commercial and residential installations. Featuring a 63A rated current, 4-pole configuration, 300mA sensitivity, and Type B operation at 400VAC, this device effectively detects and prevents earth leakage faults to ensure a secure electrical environment.
Advantages
This residual current device offers advanced Type B operation, meaning it is capable of detecting both sinusoidal AC and pulsating DC residual currents, as well as smooth DC components. Its robust 4-pole design and 63A capacity make it suitable for demanding electrical systems. The 300mA sensitivity provides a balanced approach to fire protection and system reliability, while the reputable Legrand DX3 series ensures high manufacturing standards and dependable long-term performance in modern electrical panels.
Suitable for
Commercial electrical installations requiring Type B residual current protection
Residential electrical panels with complex loads
Protection against earth leakage faults and electrical fires
Circuits involving equipment with smooth DC residual currents
When it may not be suitable
This device is not designed for circuits operating outside its specified 400VAC rating or for applications requiring a lower sensitivity threshold, such as direct human contact protection which typically requires 30mA devices. Additionally, it may not be necessary for basic residential circuits that do not feature loads producing smooth DC components.
