Combined circuit breaker iCV40N-C32-30-A C 32A 3N-pole 30 mA type A A9DC3732

Advanced electrical installation protection

The Acti9 iCV40 residual current circuit breaker with overcurrent protection is a compact 3P+N-pole solution providing comprehensive protection for electrical circuits. The device with a rated current of 32A utilizes C tripping characteristic, which is ideal for circuits with devices having moderate inrush currents.

Type A residual current protection with a sensitivity of 30mA reacts to sinusoidal, pulsating DC, and mixed leakage currents. Instantaneous operation guarantees immediate circuit disconnection upon detecting a hazardous situation.

Key protective functions

The device protects the installation against multiple types of hazards simultaneously. The overcurrent protection eliminates the effects of short circuits and conductor overloads, while the residual current component protects against electric shock from indirect contact and minimizes the risk of fire caused by leakage current.

The Icn short-circuit breaking capacity of 6000A (according to EN/IEC 61009-2-1) ensures reliable operation even in demanding conditions. Insulation voltage Ui=440V and impulse withstand strength of 0,25kA guarantee safe operation in standard installations.

Practical service solutions

Two unique VisiTrip indicators significantly reduce servicing time by precisely indicating the faulty circuit and the type of fault. This feature is particularly valuable for installers during diagnostics and repairs.

The device operates in temperatures from -25°C to +60°C at a frequency of 50/60Hz. A width of 5 modules (44mm depth) facilitates mounting in standard distribution boards. Conductor cross-sections from 1mm² to 16mm² (single-core) or from 1mm² to 10mm² (multi-core) ensure connection versatility.

The IP20 protection rating protects against contact with live parts, and the simultaneous disconnection of the N pole simplifies installation and improves user safety.
