The Legrand DX³ 411506 residual current circuit breaker is designed to detect earth leakage currents and disconnect the circuit when they reach the set threshold. It features 2 poles, a rated current of 63 amperes, 30 milliamperes sensitivity, and type AC technology for detecting sinusoidal alternating residual currents.
With a rated voltage of 230 volts AC, a compact format of just 2 modules, and DIN rail mounting, this DX³ RCD is suitable for electrical panels where high-rated residual current protection is required in single-phase circuits.
Reference 411506 belongs to Legrand's DX³ range of residual current circuit breakers. Its 2-pole configuration allows the simultaneous disconnection of the circuit conductors when the device detects a residual current above the set value.
Its rated current of 63 amperes determines the current that can flow through the RCD under normal operating conditions, always respecting the installation conditions and overcurrent protection defined for the circuit.
The Legrand 411506 features a rated residual current of 30 milliamperes. The device continuously compares the current flowing through the live conductors and trips the circuit when it detects an imbalance corresponding to an earth leakage above the specified threshold.
This sensitivity is used as additional residual current protection against the risk associated with electric shock and leakage currents, within the conditions established by the applicable installation regulations.
This model belongs to class AC. Residual current devices of this type are intended to detect sinusoidal alternating residual currents.
The choice of residual current device type should be made taking into account the loads connected to the circuit. For installations with electronic equipment capable of generating other forms of residual current, type A, F, B or other specific technologies may be required.
The residual current device is designed for a rated voltage of 230 volts AC and a frequency of 50 hertz.
Its rated insulation voltage is 250 volts and the rated impulse withstand voltage reaches 4 kilovolts.
Legrand specifies a 10-kiloamp Icw short-circuit withstand rating for reference 411506. It also indicates an impulse withstand capacity of 0.25 kiloamperes.
It is important to note that this product is a residual current circuit breaker and does not include magnetothermal protection against overloads and short circuits. It must be installed together with the appropriate overcurrent protection devices for the circuit.
The residual current device is designed to detect insulation faults that cause current to flow to earth. When the leakage exceeds its rated sensitivity, the mechanism opens the circuit to interrupt the supply.
In addition to helping protect against the risk of electric shock, the detection of persistent leakage currents helps limit risks arising from insulation faults in the installation.
The Legrand DX³ 411506 occupies a width equivalent to 2 modules, making it easy to integrate into electrical panels alongside miniature circuit breakers, contactors and other modular devices.
It is designed for DIN rail mounting and has an installation depth of 44 millimeters.
These dimensions make it possible to accurately plan the space required inside the distribution board.
The residual current device includes screw connection terminals and accepts both cable and compatible busbar systems.
The connection capacities specified by Legrand are:
This terminal capacity makes it easy to integrate into installations with high currents and different conductor cross-sections.
Reference 411506 allows power supply from the top or bottom, providing flexibility during panel design and wiring.
The device supports connection by cable and compatible busbar, making it easy to combine with other modular components in the Legrand range.
The residual current device offers an IP20 protection rating once wired according to the manufacturer's conditions.
Its mechanical impact resistance is IK04, while the front face provides protection against direct contact suitable for use in properly installed electrical panels.
The Legrand 411506 is designed to operate in ambient temperatures between -25 and 60 degrees Celsius.
For storage, the manufacturer specifies a range between -40 and 70 degrees Celsius. The product has a pollution degree 2.
Legrand indicates that this residual current circuit breaker can be combined with compatible auxiliary devices from the DX³ range, expanding the possibilities for control, signaling or actuation according to the needs of the electrical panel.
It also includes a front identification space, making it easier to label the protected circuit and carry out subsequent inspection or maintenance operations.
The Legrand DX³ 411506 residual current circuit breaker is developed in accordance with IEC/EN 61008-1, applicable to residual current-operated circuit breakers without integral overcurrent protection.
This feature confirms that its function is specifically residual current protection and that it must be coordinated with the corresponding magnetothermal protection of the installation.
The Legrand DX³ 411506 combines a rated current of 63 amperes, 30-milliamp sensitivity and AC residual current detection in a compact 2-module format.
Its DIN rail mounting, 10-kiloamp Icw short-circuit withstand rating, wide connection range and compatibility with DX³ auxiliary devices make it easy to integrate into electrical panels that require bipolar residual current protection at 230 volts.
