Residual current circuit breaker with overcurrent protection 1P+N 6kA C 25A/30mA Type AC ADC975D

Protection and safety in one device

Residual Current Device with Overcurrent protection is a compact solution that combines short-circuit and personal protection functions. The 1P+N model with a rated current of 25A and a sensitivity of 30mA (Type AC) provides comprehensive protection in electrical circuits. The rated short-circuit breaking capacity of 6kA guarantees effective disconnection in the event of a failure, minimizing the risk of damage and fire.

Versatility and easy installation

The device, 2 modules wide (36mm), is designed for mounting on a TH35 rail. The cross-section of solid wires from 1 to 25 mm² and stranded wires from 1 to 16 mm² ensures compatibility with various types of installations. The C tripping characteristic means that the circuit breaker reacts quickly to overloads but is more tolerant of short-term current surges – which is particularly important with loads with motors or transformers.

Specification for professionals

The circuit breaker meets the requirements of IEC 60947-2 and EN 61009-1 standards, confirming its reliability and safety. The rated insulation voltage Ui is 500V, and the rated impulse withstand voltage Uimp is 4kV. The energy limitation class is 3, and the surge category is III – which demonstrates its resistance to network disturbances. The degree of protection is IP20, which provides protection against accidental contact but does not protect against the ingress of water. The device operates in an ambient temperature from -25°C to +40°C. Additionally, the presence of a disconnected N pole simultaneously with the phase pole increases the safety level of the installation.
