Residual current circuit breaker 1P+N 25A/30mA Type A QuickConnect left N CDS225R

Residual Current Device 1P+N – Protection and Safety of the Installation

This type A residual current device (RCD) with a rated current of 25A and a tripping current of 30mA is a key element ensuring safety in electrical installations. It is used to protect people from electric shock in the event of insulation failure or equipment malfunction. Its 1P+N design means it protects both the phase and neutral conductors, increasing the effectiveness of protection. Equipped with a QuickConnect system, it simplifies and speeds up mounting on a DIN rail.

Characteristics and application

The CDS225R circuit breaker is designed for use in circuits with a rated voltage of 230V and a frequency of 50Hz. Its compact dimensions (width 2 modules, depth 70mm) allow for easy integration with existing distribution boards. The rated differential current of 30mA ensures a quick response to leakage currents, minimizing the risk of electric shock. This circuit breaker is used to protect lighting circuits, sockets in residential and auxiliary rooms, and other electrical devices requiring protection against electric shock.

Advantages and structural features

• Quick installation: The QuickConnect system significantly reduces installation time, which is particularly important for larger projects.
• High reliability: Short-circuit strength at 6kA guarantees stable operation of the device even in the event of overloads or short circuits.
• Wide range of conductors: The ability to connect solid conductors with a cross-section from 1 to 25 mm² and stranded conductors from 1 to 16 mm² ensures compatibility with various types of installations.
• Safety: Type A sensitivity means the circuit breaker reacts to both DC and AC currents, providing comprehensive protection against electric shock.
• Durable construction: IP20 protection degree protects against touching with fingers and solid objects larger than 12.5 mm.
• Versatility: Suitable for mounting on a standard DIN rail.
• Resistance to external conditions: Adapted to operate in ambient temperature from -25°C to +40°C.
• Rated impulse withstand voltage Uimp: 4kV – ensures resistance to overvoltages.
• Rated insulation voltage Ui: 500V – guarantees the safety of the internal insulation of the device.

Additional accessories (mounting adapters, locks) allow you to adapt the circuit breaker to the specific needs of the installation.
