Residual current circuit breaker with overcurrent protection 3x1P+N 6kA B 16A/30mA Type A QC/QBB ADZ316D

Multifunctional switch for safety and convenience

This Residual Current Circuit Breaker (RCCB) with overcurrent protection combines short-circuit and leakage current protection, providing comprehensive protection for your electrical installation. It is an ideal solution for both installers and end-users who value safety and reliability. The device is designed to protect circuits in residential and commercial buildings.

Characteristics and application

The circuit breaker is characterized by a rated current of 16A and a leakage current sensitivity of 30mA, ensuring a quick response in the event of an electric shock hazard. Characteristic B provides effective protection against overloads and short circuits, and also allows for the safe starting of devices with electric motors – this characteristic allows for momentary current exceeding without unnecessary tripping. The rated short-circuit breaking capacity Icn at 6kA guarantees that the device can handle even high short-circuit currents, protecting the installation from damage. Equipped with an N pole, which disconnects simultaneously with the other poles, ensures complete protection against dangerous situations.

Advantages in practice

• Versatile application: Ideal for protecting lighting circuits, socket outlets and electrical appliances in residential and commercial buildings.
• Safety first: Provides protection against electric shock and damage to the installation caused by short circuits and overloads.
• Fast response: 30mA sensitivity guarantees quick detection of leakage currents and immediate circuit disconnection.
• Easy installation: Compact dimensions (4 modules) and quickconnect system facilitate and speed up installation.
• Durable construction: Made of high-quality materials, resistant to mechanical damage and weather conditions (operating temperature from -25°C to 70°C).
• Locking: Has a lock preventing accidental switching on of the circuit breaker after it has been switched off by the protection.
• Compliance with standards: Meets the requirements of IEC 60898-1 and IEC 61009-1 standards, which guarantees its safety and reliability.
• Flush mounting: Possibility of flush mounting increases the aesthetics of the installation.
