Arc fault detection device with overcurrent and residual current protection 1P+N 6kA B 16A ARF916D

Arc fault detector with overcurrent and residual current protection – comprehensive protection for installations

This arc fault detector with overcurrent and residual current device 1P+N is an advanced solution that combines three protective functions in one device. It provides comprehensive protection of the electrical installation against the effects of short circuits, overloads and insulation faults. This is particularly important in modern buildings, where electrical installations are more complex and the risk of failure is higher. The device is designed for mounting on a DIN rail and is 3 modules wide, making it easy to integrate into an existing system.

Multifunctionality and safety

The detector combines the functions of an overcurrent circuit breaker (16A, B characteristic), a residual current circuit breaker (30mA, type A) and an arc fault detection device (AFDD). This ensures effective protection against:

• Overloads and short circuits: The overcurrent circuit breaker protects the circuit against damage caused by excessive current draw.
• Electric shock: The residual current circuit breaker quickly disconnects the power supply in the event of a current leakage to earth.
• Fires caused by arcing: The arc fault detector recognizes unusual current disturbances that can lead to ignition, especially in concealed installations.

Application and benefits

The device is ideal for both new and modernized installations. It is particularly recommended for residential buildings, especially those made of flammable materials (e.g. wood), as well as for prefabricated buildings. Its use allows for:

• Increased safety of users and property.
• Minimizing the risk of fire caused by electrical installation failure.
• Meeting legal requirements regarding electrical safety.
• Simplifying installation by combining three functions in one device – saving space in the distribution board and installation time.

Design and technical parameters

The detector has been designed for easy installation and use. It features modern quickconnect and quickbusbar connections, which significantly reduce installation time. The device is characterized by high reliability and durability confirmed by IEC 60898-1 and IEC 61009-1 standards. The rated short-circuit breaking capacity is 6 kA, which ensures effective protection even in the event of serious failures. The device operates at a rated voltage of 230 V and a frequency of 50 Hz, and its operating temperature range is from -25°C to +40°C. Additionally, it has a protection degree of IP2X, which protects against access to live parts with a finger.
