Residual current circuit breaker with overcurrent protection 4P 6kA C 32A/30mA Type A ADM482C

Residual Current Circuit Breaker with Overcurrent Protection 4P 6kA C 32A/30mA Type A is a comprehensive protection for electrical installations, combining the functions of an overcurrent and residual current circuit breaker. The device is designed to protect people and equipment from the effects of electric shock, short circuits and overloads. Its C characteristic design provides effective protection for circuits with devices generating surge currents, such as motors or transformers.

Protection and Application

This circuit breaker is used in electrical installations in residential, commercial and industrial buildings. It protects against the effects of leakage currents to earth, minimizing the risk of electric shock, and also protects against damage to the installation caused by overloads or short circuits. The short-circuit breaking capacity of 6kA guarantees safety even in the event of serious failures. Additionally, this model has a mechanical lock, preventing accidental switching on after switching off due to a failure – this is important for ensuring the continuity of safe operation of the installation.

Characteristics and Construction

The device is characterized by a four-pole design (4P), which means it protects all phase and neutral conductors. The rated differential current of 30mA provides high sensitivity to leakage currents, and type A means that the circuit breaker reacts to sinusoidal and pulsating alternating currents – typical of most household appliances. A width of 4 modules allows for easy mounting in standard electrical distribution boards. Flush mounting further enhances the aesthetics of the installation. Conductor cross-sections of solid wires from 1 to 25 mm² and stranded wires from 1 to 16 mm² provide great flexibility when selecting power cables. Energy limitation class 3 indicates the circuit breaker's ability to withstand short-circuit energy without damage.
