Residual current circuit breaker with overcurrent protection 1P+N 6kA B 20A/30mA Type AC ADC920D

Safety and reliability in one device

The Hager ADC920D residual current circuit breaker with overcurrent protection is a compact and effective solution, providing comprehensive protection for electrical installations. The device combines the functions of an overcurrent circuit breaker (B characteristic) and an AC type residual current circuit breaker, guaranteeing effective protection against overload, short circuit and electric shock. Designed to operate in AC 240V networks, with a rated current of 20A and a sensitivity of 30mA, it is a reliable safety element in every circuit.

Universal application and easy installation

The ADC920D circuit breaker is used in both home installations and public utility facilities. Its modular design (2 modules) allows for easy mounting on a 35mm DIN rail, and the screw-cage terminals ensure secure and quick connection of wires with a cross-section from 1 to 25 mm² (solid) or 1 to 16 mm² (stranded). This makes it easy and quick to install for installers, and safety and comfort for end users.

Key features and benefits:

• Comprehensive protection: Combining overcurrent and residual current functions in one device minimizes the risk of failure and ensures complete safety.

• High breaking capacity: The rated short-circuit breaking capacity of 6kA guarantees effective disconnection of the circuit in the event of a short circuit.

• B characteristic: Provides a quick response to overloads and short circuits, protecting the installation from damage. The B characteristic allows it to react more slowly to short current surges, so it tolerates starting devices with a motor well.

• AC sensitivity: Detects sinusoidal leakage currents, providing protection against electric shock.

• Wide operating temperature range: The ability to operate in a temperature range from -25°C to 40°C makes the device suitable for various environmental conditions.

• Operation indicator: An optical indicator informs about the operation of the circuit breaker, making it easier to locate the problem.

• Compliance with standards: Meets the requirements of IEC/EN 61009-1 standards, confirming its high quality and safety.

• Wire connection cross-section: The ability to connect wires with a cross-section of up to 25mm² provides flexibility in choosing the appropriate cables.

The Hager ADC920D circuit breaker is characterized by a rated current of 20A, a B tripping characteristic and a short-circuit breaking capacity of 6kA. It is an AC type residual current circuit breaker with a sensitivity of 30mA, designed for mounting on a DIN rail with a width of 2 modules. The rated insulation voltage is 500V.

The Hager ADC920D circuit breaker is an investment in safety and peace of mind – both for professionals performing electrical installations and for end users benefiting from the protected installation.
