Residual current circuit breaker 3P+N 25A/30mA Type A QuickConnect CDS425D

Safety and protection in your electrical installation

The 3P+N 25A/30mA Type A QuickConnect CDS425D residual current device (RCD) is a key element ensuring safety in every electrical circuit. Its function is to quickly detect and disconnect the power supply in the event of a short circuit to earth or overload, minimizing the risk of electric shock and equipment damage. This four-pole (3P+N) circuit breaker is designed to protect circuits with a rated current of 25A, and its 30mA sensitivity guarantees a quick response to dangerous leakage currents.

Design and installation – speed and reliability

The circuit breaker has been designed with easy and quick mounting on a DIN rail in mind. The QuickConnect system significantly simplifies the connection of wires, saving time for both installers and end-users performing minor maintenance work. The device width of 4 modules allows for efficient use of space in the distribution box. Solid construction and high-quality materials ensure long-lasting and trouble-free operation.

Application and technical parameters – for professionals and demanding users

This Type A residual current device is ideal for use in circuits with devices generating leakage currents, such as switch-mode power supplies or certain types of LED lighting. The rated voltage of 400V and high short-circuit strength (6kA) guarantee reliable operation even in difficult operating conditions. The cross-section of the connectable solid wire up to 25mm² and stranded wire up to 16mm² ensures compatibility with most standard electrical installations. Additionally, the mechanical lock prevents accidental adjustment of the circuit breaker, increasing safety. The rated impulse withstand voltage Uimp is as high as 4kV, which indicates high resistance to overvoltage. The degree of protection IP20 means protection against touching with a finger and solid objects larger than 12.5 mm.
