Residual Current Device (RCD) iID-40-4-30-A 40A 4-pole 30mA type A A9Z21440

Advanced protection of electrical installations with iID-40-4-30-A circuit breaker

This four-pole residual current circuit breaker from Schneider Electric, with a rated current of 40A and a tripping current of 30mA (Type A), is a key element ensuring safety in electrical installations. It provides effective protection against electric shock for end-users and protects the installation from the effects of short circuits to earth. It is indispensable in residential, commercial and industrial buildings.

Functionality and user comfort for professionals and users

The iID-40-4-30-A circuit breaker stands out with a number of features that facilitate installation and operation. Double terminals allow connection of two cables with different cross-sections, increasing installation flexibility. The Visi-Trip optical indicator immediately signals the tripping of the circuit breaker, making it easier to locate the problem. Removing a single device from the DIN rail is simple and does not require removing the entire rail. Additionally, the ability to check the correct operation with the "T" test button once a year for the first 7 years of use ensures the proper functioning of the protection system. The neutral conductor located on the left side facilitates alignment with overcurrent circuit breakers, speeding up installation work.

The circuit breaker is designed to operate in a wide range of conditions. The rated short-circuit current reaches 10kA, and the rated voltage is 400V with an insulation voltage of 500V. Its width is 4 modules (72mm), which allows for efficient use of space in the distribution board. It is adapted to work at temperatures from -25°C to 60°C, making it reliable even in difficult environmental conditions. It withstands a rated impulse voltage of up to 6kV, and the IP20 degree of protection provides basic protection against touch and dust. The possibility of using cables with a cross-section from 1mm² to 35mm² (solid) or from 1mm² to 25mm² (stranded) gives great freedom in choosing the appropriate cables. Power losses are 3.8W at a frequency of 50/60Hz. It is equipped with a lock preventing accidental opening of the housing and complies with the EN/IEC 61008-1 standard.
