Residual current circuit breaker Acti9 iID-25-2-30-B-SI 25A 2-pole 30mA type B-SI A9Z61225

Safety and reliability in your electrical installation

The Acti9 iID-25-2-30-B-SI residual current circuit breaker is a key element ensuring the protection of people and equipment in electrical installations. Designed for both professional installers and end-users, it guarantees a quick response in the event of a failure and minimizes the risk of electric shock. DIN rail mounting simplifies integration with existing systems, and compact dimensions (4 modules) save space in the distribution board.

Protection tailored to your needs

This two-pole circuit breaker with a rated current of 25A and a sensitivity of 30mA type B-SI effectively protects against the effects of short circuits and earth leakage currents. Characteristic B ensures that the circuit breaker does not trip unnecessarily during short-term overloads, e.g., when starting motors, but reacts instantly in the event of a hazard. The rated impulse withstand voltage of 6kV further increases its resistance to sudden voltage surges.

Comfort of installation and use

The Acti9 iID-25-2-30-B-SI circuit breaker has been designed for easy installation and intuitive operation. The ability to connect solid conductors with a cross-section of 1…35 mm² and stranded conductors 1…25 mm² provides great flexibility during installation. It operates in a wide range of ambient temperatures (-25…60°C), making it suitable for use in various conditions. Additionally, the possibility of expansion with accessories allows you to adapt the functionality to individual needs. The IP20 degree of protection provides protection against accidental contact. Power losses of only 0.7W minimize the impact on the energy efficiency of the installation.
