Circuit-breakers with integral residual current protection, 4-pole, 160 A, [!--V:adInhaltTextb

Circuit-breakers with residual current trip (CBR) switch high currents, protect equipment, cables and lines against overcurrent and protect people against electric shock. DFL 8 are compact devices with integrated auxiliary switch and terminals for large conductor cross-sections. Type B switches are AC-DC sensitive at frequencies of 0 Hz (smooth residual currents) to 150 kHz. They have increased resistance to surge currents and lightning. Switches with the characteristic curve SK ensure fault protection and a high system availability. They are characterised by a lower response sensitivity at higher frequencies. This means that system-related faulty tripping is largely prevented. For switches of this variant, the residual response current can be individually set in levels for the application in question (0,3 A, 0,5 A, 1 A). The non-response lag time can also be adjusted in levels accordingly. Selective residual current circuit-breakers are therefore possible in systems with stacked distribution boards. Devices in the standard design are intended for monitoring circuits with a rated voltage of 230 V, 400 V and a rated frequency of 50 Hz.

stacked power supply systems with TN-S, TT, and TN-C-S networks with high short-circuit performance in purpose-built buildings and industrial facilities , In IT networks, the residual current trip of the CBR can be set to switch off in the event of a second earth fault. , Thanks to its AC/DC sensitive residual current trip, this AC/DC sensitive CBR is especially suitable for protecting systems with electronic equipment that is not galvanically isolated from the mains at its inputs. , use for residual current protection in TN-C networks is excluded
