Residual current circuit breaker IDK-A25-30-4 A9Z01425

Residual Current Device (RCD) IDK-A25-30-4 is a reliable protection for electrical installations, designed for both residential and more demanding environments. The device with a rated current of 25A and a sensitivity of 30mA, type A, effectively protects against electric shock, reacting to both sinusoidal and pulsating DC currents. The four-pole design allows for the protection of the entire circuit.

Features and application

This circuit breaker is widely used in electrical installations where protection of people and equipment against the effects of short circuits and leakage currents is required. Mounting is on a DIN rail, ensuring easy installation and integration with existing infrastructure. A width of 4 modules allows for efficient use of space in the distribution board. The use of high-quality materials guarantees long-lasting and trouble-free operation of the device. Additionally, the placement of the N conductor on the left side facilitates alignment with overcurrent circuit breakers – a solution appreciated by installers.

Parameters and benefits

The IDK-A25-30-4 circuit breaker is characterized by a high short-circuit strength of 10kA, which ensures its stable operation even in the event of large voltage surges. The ability to connect wires with a cross-section from 1 to 35 mm² (solid) and from 1 to 25 mm² (stranded) provides great flexibility during installation. It is worth noting the rated impulse withstand voltage Uimp of 4kV – this confirms resistance to sudden voltage spikes. Power losses of only 2.7W minimize the impact on the energy efficiency of the installation. This means that the device not only ensures safety but also helps to reduce operating costs. Additionally, the possibility of additional equipment allows you to adapt the circuit breaker to the specific needs of a given installation.

Remember to regularly check the correct operation of the circuit breaker using the "T" test button – it is recommended to do this every six months for the first 7 years of use. This is a simple operation that allows you to be sure that the device is ready to operate when needed.
