Residual current circuit breaker with overcurrent protection 1P+N 10kA C 16A/30mA Type A ADA566D

Safety and reliability in your electrical installation

Hager ADA566D residual current circuit breaker with overcurrent protection is a key element in protecting the electrical installation, combining protection against overload and short circuit with protection against electric shock. The device is intended for use in 230V AC circuits, providing comprehensive protection for both the installation and users. A 1P+N design means it protects both the phase and neutral conductors, increasing the level of safety.

Functionality and technical parameters

The circuit breaker is characterized by a rated current of 16A and a residual current sensitivity of 30mA (Type A), making it an ideal solution for protecting lighting circuits, socket outlets and electrical devices exposed to the risk of electric shock. Characteristic C provides delayed tripping during short-term overloads, which is particularly important when connecting devices with motors or other elements generating high starting current – it will not cause unnecessary disconnection of the circuit when starting the device. The rated short-circuit breaking capacity Icn is 10kA, which guarantees effective disconnection of the circuit in the event of a serious failure.

• Versatile mounting: Flush mounting option simplifies integration with different types of installations.
• Wide range of wires: Supports solid wires with a cross-section of 1-25 mm² and stranded wires 1-16 mm² ensuring compatibility with most wiring used in residential and commercial construction.
• Locking: Integrated lock prevents accidental switching on of the circuit breaker after it has been switched off by the protection device.
• Compliance with standards: Meets the requirements of IEC 60898-1 and IEC 60947-2 standards, guaranteeing safety and reliability.
• Compact dimensions: 2 module width allows for efficient use of space in the switchgear cabinet.
• Resistance to external conditions: Suitable for operation in temperatures from -25°C to 40°C.

Application and benefits

This residual current circuit breaker is used in a wide range of electrical installations – from single-family homes, through apartments, to commercial and industrial buildings. It provides effective protection against electric shock, prevents fires caused by short circuits and protects electrical devices from damage due to overloads. Thanks to characteristic C, it minimizes the risk of unnecessary tripping caused by short-term current surges, which translates into user comfort and system reliability. In addition, combining overcurrent and residual current functions in one device saves space in the switchgear cabinet and simplifies installation.
