Residual current circuit breaker with overcurrent protection 1P+N 6kA B 16A/30mA Type A QuickConnect ADS916D

Residual Current Circuit Breaker with Overcurrent protection 1P+N is a reliable protection for electrical installations, combining the functions of an overcurrent and residual current circuit breaker. The ADS916D model from Hager, with a rated current of 16A and a tripping current of 30mA, provides comprehensive protection against the effects of overloads, short circuits and electric shock. Type A application ensures that the circuit breaker effectively responds to alternating and direct leakage currents, which is particularly important in modern installations with electronic devices.

Functionality and Application

The device is designed to protect circuits in single-phase installations with a voltage of 240V. Its compact size – 2 modules wide – allows for easy mounting in electrical distribution boards, both in residential and commercial buildings. The circuit breaker is used to protect lighting circuits, socket circuits and electrical appliances requiring protection against leakage currents. QuickConnect system provides fast installation and easy connection of wires.

Technical Characteristics and Safety

The circuit breaker is characterized by a high short-circuit breaking capacity – up to 6kA – which guarantees effective disconnection of the circuit in the event of a serious failure. Characteristic B provides fast tripping in case of overloads and short circuits, minimizing the risk of damage to the installation and equipment. Additionally, a mechanical lock prevents accidental re-engagement of the circuit breaker after it has been switched off by a residual current or overcurrent. Energy limitation class 3 confirms high effectiveness of protection against the effects of short circuits. Compliance with IEC 60898-1 and IEC 61009-1 standards ensures safety of use and compliance with applicable regulations. The rated impulse withstand voltage Uimp is 4kV, which increases resistance to overvoltages.
