EAN: 4014712111127 - manufacturer-number: DFS4040-4/0,03-AR - RCCB DFS4 040-4 / 0.03-AR, number of poles = 4, rated voltage = 400 V, rated current = 40 A, rated residual current = 30 mA, rated insulation voltage Ui = 400 V, rated surge voltage resistance Uimp = 4 kV, mounting type = DIN rail , Residual current type = A, selective type = no, short-time delayed type = no, short-circuit strength (Icw) = 10 kA, surge current resistance = 0.25 kA, frequency = 50 Hz, additional devices possible = yes, with locking device = no, protection class ( IP) = IP20, width in graduation units = 4, installation depth = 69 mm, ambient temperature during operation = -25..40 ° C, degree of pollution = 2, connectable conductor cross-section stranded = 1.5..50 mm², connectable conductor cross-section solid = 1 , 5..50 mm², residual current circuit breakers (RCCB) switch off the power supply if dangerously high residual currents occur. In this way you protect people, animals and plants. DFS 4 are two- or four-pole residual current circuit breakers for single- or three-phase networks. In the standard version, the compact devices are four division units narrow. They are available with many different types of residual current and designs with rated currents up to 125 A. The large double-level terminals can also accommodate large conductor cross-sections. The triggered position of the multi-function switch knob makes troubleshooting easier. The free label software helps with labeling. Type A switches are pulse and AC sensitive. This function is independent of the mains voltage. Standard devices are designed for the monitoring of circuits with a rated voltage of 230 V / 400 V and a rated frequency of 50 Hz. Properties: mains and auxiliary voltage-independent triggering, sensitive to AC and pulsating DC residual currents (type A) small size for all rated currents, high short-circuit strength, double-sided terminals for large conductor cross-section and rail connection, switch position indicator, viewing window for labeling labels, multi-function switch toggle with three positions: & quot, a & quot ,, & quot, from & quot,, & quot, triggered & quot,, also available in the & quot, HD & quot version, connection C1 neutral conductor position on the right, mounting type: quick fastening on mounting rail, installation position as required, feed direction as required, areas of application: power supplies for residential and functional buildings and industrial plants with TN-S, TT and TN-CS networks. Residual current circuit breakers of this series can be provided in IT networks for tripping in the event of a second fault. Use in TN-C networks and to protect systems is excluded. in which electronic equipment can cause smooth DC residual currents or residual currents with frequencies not equal to 50 Hz. There is no comprehensive protection here. For such applications we recommend our AC / DC sensitive residual current circuit breakers (type B or B +). - DFS4 040-4/0,03-A R
