Residual current circuit breaker with overcurrent protection 1P+N 10kA B 16A/30mA Type A ADA516D

Residual Current Circuit Breaker with Overcurrent Protection – Comprehensive Installation Protection

This 1P+N circuit breaker combines the functions of an overcurrent and residual current device, providing comprehensive protection for electrical circuits. A rated current of 16A combined with a sensitivity of 30mA guarantees effective protection against overload, short circuit and electric shock. It is an ideal solution for both home and professional installations.

Construction and application

The ADA516D circuit breaker is designed for mounting on a DIN rail in electrical distribution boards. Its compact dimensions (2 modules wide) allow for efficient use of space in the distribution cabinet. The use of characteristic B ensures fast tripping in the event of short circuits, while allowing for trouble-free starting of devices with electric motors, which generate short-term inrush currents. Type A provides protection against alternating leakage currents, which is crucial for the safety of users and the installation.

Key features and benefits

• Combined function: One circuit breaker acts as both overcurrent and residual current protection – saving space and costs.
• High breaking capacity: Rated short-circuit breaking capacity of 10kA ensures effective disconnection of the circuit in the event of a serious failure.
• Wide range of applications: Suitable for protecting lighting, socket outlets and other electrical devices with a power of up to 16A.
• Safety of use: Sensitivity of 30mA ensures a quick response to leakage currents, minimizing the risk of electric shock.
• Flush mounting: Possibility of flush mounting increases the aesthetics of the installation.
• Locking: Integrated lock prevents accidental switching on of the circuit breaker after it has been switched off by the protection.
• Connection flexibility: Possibility of connecting solid conductors (up to 25mm²) and stranded conductors (up to 16mm²) using screw or biconnect terminals.
• Resistance to external conditions: Designed to operate at temperatures from -25°C to 40°C, ensuring reliable operation even in difficult conditions.

The ADA516D circuit breaker is a solid and reliable device that will meet the expectations of both professional installers and demanding end users. Its high quality of workmanship and compliance with safety standards guarantee long-term and trouble-free operation.
