Residual Current Device (RCD) IDK-40-2-30-A 40A 2-pole 30mA type A A9Z01240

Protection and safety in your electrical installation

Residual Current Device (RCD) IDK-40-2-30-A is a key element ensuring safety in electrical installations. The device, with a rated current of 40A and a sensitivity of 30mA, effectively protects against electric shock, reacting to both sinusoidal and pulsating DC currents – type A. It is ideal for residential and similar buildings.

Installation and functionality for professionals

The RCD is mounted on a DIN rail, ensuring quick and easy installation. The two-pole design (2P) combined with the N pole on the left side facilitates alignment with overcurrent circuit breakers, saving time and space in the switchgear cabinet. Serrated terminals guarantee a secure connection of wires with a cross-section from 1 to 35 mm² (solid) or 1 to 25 mm² (stranded). The RCD also has a "T" test button, allowing for regular testing of its operation – testing is recommended every six months for the first 7 years of use.

Solid construction and technical parameters

The RCD is characterized by a high short-circuit strength of 10 kA and a rated voltage of 230V. The rated insulation voltage Ui is 440V, and the rated impulse withstand voltage Uimp is 4 kV. The device operates at a frequency of 50/60 Hz and has a protection degree of IP20. Power losses are 3.6W, and the ambient temperature in operating conditions ranges from -25 to 40°C. The width of the RCD is 2 modules, allowing for optimal use of space in the switchgear cabinet. An additional advantage is the possibility of expanding with additional equipment.
