Residual current operated circuit-breaker with integral overcurrent

protection as Fire protection switch,sensitive to pulsating and

alternating currents Type A

Function

Arc-fault detection devices(Fire protection switch, AFDD) are designed to protect serial and parallel fault arcs in accordance with EN62606(DIN VDE 0100-420).They are commonly referred to as fire protection switches. They must be installed in permanently installed final circuits up to 40A. for example. facilities at risk of fire or public institutions.They are also recommended for bedrooms and for final circuits with high connection loads.The devices detect high-frequency arc faults, such as those occurring as a result of cabling defects. The early recognition and switching off of the final circuit. which may occur as a result in the case of an emergency. prevent thermal effects of arc faults The risk of fire resulting from incorrect electrical installation is significantly reduced.The reason for tripping is indicated by an LED colour code on the front of the device. BESTAFDD 1 are compact combination devices with a triple function: arc fault detection, line protection and residual current trip.They protect systems in the event of a short-circuit and overload as per the requirements of VDE o1o Part 430, and protect persons,farm animals and material items in the event of earth leakage currents as per VDE 0100 Part 410.The RCBO component works dependent of the mains voltage.Residual current type A allows the detection of sinusoidal AC currents and pulsating DC residual currents. The contact position indicators and the display tripped by residual current provide a quick overview of the operating status of the device. The devices up to 40 A devices have a rated switching capacity of 6 kA.The line protection with characteristic B ensure standard protection for lighting and socket circuits. Devices in standard design are intended for monitoring circuits with a rated voltage of 230 V and a rated frequency of 50 Hz.

Features

combination device with three functions, 1P+N(1Module), Variable neutral-pole position, AFDD as per IEC/EN-62606, RCBO as per IEC/ EN61009, continuous self-monitoring, mains-voltage-dependent tripping of the RCCB/MCB functions. Display AFDD reason for tripping. Contact position indicators, Residual current tripping indicator, compact design for all rated currents, high short-circuit resistance, strain-relief clamps with protection against wires being lodged behind them, tri-stable snap-in slider for easy mounting and removal.

Applications

Protection of circuits in residential and purpose-built buildings as well as industrial facilities with TN-S and TN-C-S networks. Not permitted for use in systems with TN-C networks; not permitted for protecting circuits in which the power electronics equipment may cause smooth DC residual currents or residual currents with frequencies not equal to 50 Hz.

Product Description:

Combined AFDD RCBO is a reliable and safe device used to detect and interrupt arc fault in residential and commercial buildings. It is designed for a 35 mm mounting rail, with a thermoplastic housing material and a rated voltage of 240V. With a rated insulation voltage of 250V, it is able to support rated current up to 40A. The device is composed of two components: an Arc Fault Detection Device (AFDD) and a Residual Current Circuit Breaker with Overload (RCBO) protection. The AFDD is used to detect and interrupt arc fault by monitoring electrical current for any anomalous behavior that could indicate an arc fault. If an arc fault is detected, the RCBO will block the current to avoid any further damage. The Combined AFDD RCBO is an effective solution to ensure maximum safety in both residential and commercial buildings.
