Residual current circuit breaker and miniature circuit breaker combination as fire protection swi... – Doepke – 09961302 – 4014712235809: FI/LS combination as fire protection. DAFDD 1 B16/0,03/2-A number of poles 2, rated voltage 240V, rated current 16A, rated residual current 0.03A, residual current type A, energy limitation class 3, rated breaking capacity according to EN 61009 10kA, frequency 50Hz, tripping characteristic B, overvoltage category 3, degree of pollution 2 , width in modular units 3, installation depth 70mm, additional devices installed at the factory AFD unit, rated switching current for additional device 16A, rated voltage for additional device 240V, type of control voltage for additional device AC, degree of protection (IP) IP20, AFD unit, arc fault protection devices (AFDD), reduce the risk of fire due to defects in the electrical installation. When serial and parallel arcing faults occur, they switch off the affected part of the system. According to DIN VDE 0100-420, arc fault detection devices are recommended for rooms with sleeping accommodation, rooms and places with a particular risk of fire, rooms and places made of components with combustible building materials, and rooms and places where irreplaceable goods are at risk. DAFDD 1 compactly combine arcing fault detection with line and residual current protection. Contact position displays and the residual current tripped display provide a quick overview. The RCBO part offers protection against type A fault currents, short circuits and overloads, independent of the mains voltage. Switches with tripping characteristic B are the standard protection for light and socket circuits. The standard version is optimized for monitoring circuits with a rated voltage of 230 V and a rated frequency of 50 Hz. Properties: Combination device with three functions, two-pole, variable neutral conductor position, AFDD according to IEC/EN-62606, RCBO according to IEC/EN-61009, continuous self-monitoring of the AFD unit, mains voltage-independent tripping of the RCBO and LS functions, display of AFDD tripping reason, Contact position indicator, residual current tripped indicator, compact size for all rated currents, high short-circuit strength, clamping yoke terminals with rear protection, tristable locking slides for easy installation and removal, type of installation: quick attachment to DIN rail, installation position any, feed from below, areas of application: protection of circuits in residential and commercial buildings as well Industrial plants with TN-S and TN-CS networks. Use in systems with TN-C networks and to protect circuits is excluded. in which power electronics equipment can cause smooth DC fault currents or fault currents with frequencies not equal to 50 Hz.
