DPN N VIGI C32A, 30mA, type AC, 1-pole +N residual current circuit breaker with overcurrent protection A9D31632

Protection of Single-Phase Circuits in a Single Device

This device combines the functions of an overcurrent circuit breaker and a residual current device, providing comprehensive protection for single-phase installations against overloads, short circuits, and electric shock. Thanks to the use of C tripping characteristic, the device reacts more slowly to short-term current surges, making it an ideal choice for circuits powering motor-driven equipment (e.g., pumps, fans) or lighting with converters that generate higher inrush currents. The rated current of 32 A and sensitivity of 30 mA (Type AC) ensure safety for people and property in standard residential and office installations, detecting even minor earth leakage currents.

Ease of Installation and Network Status Diagnostics

A key advantage of this model is its compact design with a width of 2 modules, allowing space savings in the distribution board while maintaining full 1P+N functionality. Installers will appreciate the ability to connect conductors with a cross-section from 1 to 16 mm² (solid) or 1 to 10 mm² (stranded), eliminating the need for additional end fittings for smaller cables. The device is equipped with advanced visualization systems:

• Two-part lever – immediately indicates whether tripping was caused by short-circuit/overload current or by residual current leakage.
• Visi-Trip indicator – a white-red signal confirming electrical contact tripping.
• Visi-Safe indicator – a green LED indicator that visually confirms physical contact opening, ensuring no voltage is present at the output before touching conductors.

This integration of diagnostic functions significantly reduces fault-finding time in distribution boards. There is no need to dismantle the entire busbar system when replacing a faulty component – simply disconnect the specific device, which speeds up maintenance work and reduces the risk of errors during repairs.

Compliance with Standards and Operating Conditions

The device is designed for operation in environments with pollution degree 3 and has insulation class 2, ensuring safety even under more demanding operating conditions. The rated short-circuit breaking capacity is 6 kA, and the energy limitation class is 3, meaning rapid disconnection of short-circuit current before it reaches its peak destructive value for the installation. The rated insulation voltage is 400 V, and the impulse withstand voltage (Uimp) is 4 kV.

Device operation is possible within a wide ambient temperature range: from -5 °C to +60 °C, allowing installation not only in heated interiors but also in unheated garages or basements. Regular testing of proper operation using the "T" test button (recommended once a year) ensures that the differential mechanism functions flawlessly during the first 7 years of use.

It is important to note the key operating parameters of this model: the device supports a rated voltage of 230 V AC at a frequency of 50 Hz, and its enclosure protection rating is the standard IP20 for this class of equipment. By meeting the requirements of construction and industrial standards (EN/IEC 60898-1 and EN/IEC 61009-1), the device does not require additional fuse inserts under standard network loads. This is a universal solution combining safety with ease of operation for both professionals and end users.
