Residual current circuit breaker with overcurrent protection 1P+N 6kA C 25A/30mA Type A ADA975D

Safety and Reliability in Your Installation

This residual current device with overcurrent protection is a key element ensuring the safety of people and equipment in the electrical installation. Designed to protect circuits with a rated current of 25A, it reacts quickly to earth leakage currents (30mA), minimizing the risk of electric shock. Additionally, the built-in overcurrent protection with characteristic C protects against overloads and short circuits, ensuring continuous power supply and preventing damage.

Functionality for Professionals and Users

The device combines residual current and overcurrent protection in one unit – this saves space on the DIN rail and simplifies installation. A width of 2 modules allows for efficient use of space in the distribution board. Terminal locking ensures stable connection of wires, and single-pole disconnection of the N pole increases safety during maintenance and repairs. The rated short-circuit breaking capacity of 6kA guarantees effective disconnection of the circuit in the event of a failure, protecting the remaining elements of the installation.

Specification and Application

The device is designed to operate at temperatures from -25°C to 40°C, making it suitable for indoor applications. It is intended for AC installations with a rated voltage of 240V and a frequency of 50Hz. Compliance with IEC 60947-2 and EN 61009-1 standards confirms its high quality and safety of use. The possibility of connecting multi-wire conductors with a cross-section from 1 to 16 mm² and solid-core conductors from 1 to 25 mm² provides flexibility during installation. Characteristic C allows for trouble-free starting of devices with electric motors, which generate high starting currents – the device will not trip unnecessarily during short-term current surges. Protection degree IP20 means protection against touching with a finger, but not against a water jet – the device should be mounted in dry rooms. Energy limitation class 3 indicates its ability to limit short-circuit energy, which further increases the safety of the installation.
