Residual current circuit breaker with overcurrent protection iDPNaVigi-B10-30-AC B 10A 1-pole 30 mA type AC A9D51610

### Safety and electrical installation protection

This single-pole residual current circuit breaker with overcurrent protection, with a rated current of 10A and a sensitivity of 30mA AC, is a key element ensuring safety in every electrical installation. Designed to protect against the effects of electric shock and damage to the installation caused by overloads and short circuits, it provides a reliable protective barrier for both users and the system itself. Its compact dimensions – only 2 modules wide – allow for easy installation even in limited space within the distribution board.

Functionality and construction

The iDPNaVigi-B10-30-AC circuit breaker is characterized by a tripping characteristic of type B, which means it is particularly well suited for protecting circuits with receivers generating surge currents, such as motors or transformers. This ensures that the device reacts quickly to sudden increases in current, minimizing the risk of damage to connected devices. The two-pole lever allows for quick identification of the cause of tripping – whether the overcurrent or residual current element has operated. Additionally, Visi-Trip (white-red) and Visi-Safe (green) indicators facilitate visual control of the circuit breaker status and confirm secure disconnection of the circuit.

Installation and compliance with standards

Installation of the circuit breaker is simple and intuitive, and the ability to connect wires with a cross-section from 1 to 16 mm² (solid) or from 1 to 10 mm² (stranded) provides flexibility during installation. The device has a mechanical lock, preventing accidental re-engagement after tripping. Designed to operate at temperatures from -5°C to 60°C and meeting the requirements of overvoltage category III and pollution degree III, it guarantees reliable operation in various environmental conditions. The rated short-circuit breaking capacity of 4.5 kA ensures effective protection against the effects of short circuits. Additionally, it has protection against unwanted tripping. Regular testing with the "T" test button (once a year for the first 7 years of use) allows you to maintain the device's full efficiency for a long time.
