Residual current circuit breaker with overcurrent protection iDPNNVigi-B20-30-A B 20A 1-pole 30 mA type A A9D56620

Safety and protection in your electrical installation

This single-pole residual current circuit breaker with overcurrent protection iDPNNVigi-B20-30-A is a comprehensive solution providing protection against overloads, short circuits and electric shock. Designed to operate in installations with a voltage of 230V, with a rated current of 20A and a residual current sensitivity of 30mA (type A), it is a reliable safety element for both end users and installers.

Functionality and construction for professionals

The circuit breaker is characterized by a compact design – it occupies 2 modules on a DIN rail. Its impulse withstand voltage is 0.25 kA, and the short-circuit breaking capacity (Icn) reaches 6 kA, which guarantees an effective response in emergency situations. Characteristic B provides fast tripping in case of overloads, but allows for momentary current surges, typical for starting devices with motors. The possibility of connecting wires with a cross-section from 1 to 10 mm² (multi-stranded) or from 1 to 16 mm² (solid) provides flexibility during installation. Additionally, simultaneous disconnection of the N pole increases safety.

Indicators and operating status control

Equipped with intuitive Visi-Trip (white-red) and Visi-Safe (green) indicators, it facilitates identification of the cause of the disconnection and confirms the state of contact opening. The possibility of a one-time check of correct operation with the "T" control button (once a year for the first 7 years of use) allows for regular control of the device's efficiency. The two-pole lever informs about which element of the circuit breaker has operated – overcurrent or residual current – which significantly facilitates fault diagnosis.

Advantages for installers and users:

• Fast fault identification: VisiTrip and VisiSafe indicators allow for quick localization of the problem without the need to disassemble the device.
• High short-circuit breaking capacity: Ensures effective protection of the electrical installation against the effects of short circuits.
• Compact dimensions: Saves space in the distribution board thanks to a width of only 2 modules.
• Installation flexibility: Possibility of connecting wires of different cross-sections.
• Safety of use: Simultaneous disconnection of the N pole minimizes the risk of electric shock.
• Compliance with standards: Meets the requirements of EN/IEC 60898 and EN/IEC 60947-2 standards, which guarantees high quality and reliability.
• Resistance to environmental conditions: Designed to operate at temperatures from -25°C to 60°C and in environments with a pollution degree of 3.
