Residual Current Device (RCD) 3P+N 40A/30mA Type A QuickConnect CDS440D

Safety and reliability in electrical installations

3P+N 40A/30mA Type A QuickConnect residual current circuit breaker is a key element ensuring the protection of people and equipment in electrical circuits. The device effectively reacts to leakage currents, minimizing the risk of electric shock and preventing fires. The 3P+N design makes it ideal for protecting three-phase circuits, and the rated current of 40A allows it to be used in installations with higher power consumption.

Functionality and installation

The circuit breaker has been designed with easy and quick installation in mind. QuickConnect technology significantly speeds up the connection of wires, which is particularly important during installation work. Mounting is done on a standard DIN rail, ensuring compatibility with most electrical panels. The device width of 4 modules allows for optimal use of space in the distribution cabinet.

• Quick installation: QuickConnect system reduces installation time and simplifies wire connection.
• Versatility: Possibility of mounting on a DIN rail ensures compatibility with various distribution boards.
• High resistance: Short-circuit strength at 6kA guarantees reliable operation even in the event of overloads.
• Wide temperature range: Maintains full efficiency in the temperature range from -25°C to 70°C, making it suitable for use in various environmental conditions.
• Safety of use: Equipped with a lock preventing accidental activation or deactivation.
• Wire cross-sections: Supports solid wires with a cross-section of 1…25 mm² and stranded wires 1…16 mm².

Using a Type A residual current circuit breaker guarantees protection not only against sinusoidal currents, but also against pulsating DC currents that can be generated by modern electronic devices. The rated impulse voltage withstand of 4kV provides additional safety in the event of overvoltages in the electrical network. This makes the device perfect for use in both domestic and industrial installations.
