Residual current circuit breaker 1P+N 40A/30mA Type A QuickConnect left N CDS240R

Safety and reliability in your electrical installation

Residual Current Device (RCD) 1P+N with a rated current of 40A and a sensitivity of 30mA, with characteristic A, is a key element ensuring the protection of people and equipment against electric shock and the effects of short circuits. This model, catalog number CDS240R, combines compact size with high efficiency. It is an ideal solution for both new installations and modernization of existing ones.

Construction and installation

The RCD is designed for mounting on a DIN rail, which significantly simplifies and speeds up installation. The compact width of 2 modules allows for efficient use of space in the distribution board. The QuickConnect system ensures quick and reliable connection of wires, minimizing the time required for installation work. The cross-section of the connected solid wire is 1…25 mm², and the stranded wire is 1…16 mm², which provides great flexibility in choosing wires.

Functionality and parameters

This RCD is characterized by high surge current resistance (0.25 kA) and short-circuit strength at the level of 6 kA. The rated insulation voltage Ui is 500 V, and the rated impulse withstand voltage Uimp is 4 kV, which guarantees safe operation in various conditions. The device operates at a frequency of 50 Hz and has a protection degree of IP20. The rated differential current ldn is 30 mA, which provides effective protection against electric shock upon contact. Left N execution facilitates identification and organization of wiring in the distribution board. Additionally, the possibility of additional equipment allows you to adapt the RCD to specific installation needs.
