Overview

Circuit breakers with residual current protection (CBR) switch high currents, protect equipment, cables and lines from overcurrent and people from electric shock. DFL 8 are compact devices with an integrated auxiliary switch and connection terminals for large cable cross-sections. Type B switches are sensitive to all currents. They protect against pulse and alternating residual currents, residual currents with mixed frequencies and smooth direct residual currents at frequencies up to 150 kHz. They are resistant to increased surge currents and storms. Switches with the NK characteristic curve offer classic fire protection of 300 mA at frequencies up to 150 kHz. They are optimized for fire-prone operating sites. Switches of this variant have a fixed rated residual current of 30 mA for personal protection. They therefore guarantee fault and fire protection as well as additional protection (personal protection, protection against direct contact). Standard devices are designed for monitoring circuits with a rated voltage of 230 V/400 V and a rated frequency of 50 Hz. Properties: - fixed rated residual current of 0.03 A - rated currents from 100A to 250A, - rated voltage 230 V, 400 V AC, - four-pole, - residual current detection for smooth direct current as well as alternating and pulsating direct currents, - high tolerance to fluctuations in the auxiliary voltage when detecting residual currents type B, - mains and auxiliary voltage independent tripping for residual currents of type A and in the event of overcurrent, - high short-circuit switching capacity, - connection terminals up to 185mm - high surge current resistance, i.e. low tendency to false tripping due to transient residual currents - thresholds for instantaneous and delayed overcurrent tripping adjustable - auxiliary switch integrated Mounting type: - attachment to mounting plate - installation position as required - feed from below Areas of application: - power supplies in purpose-built buildings and industrial plants with TN-S, TT and TN-CS networks with high short-circuit power - in In IT networks, the residual current tripping of the CBR can be provided for shutdown in the event of a second earth fault. - Due to its universal current sensitive residual current tripping, this universal current sensitive CBR is particularly suitable for protecting systems with electronic equipment that is not galvanically isolated from the network on the input side. - It cannot be used for residual current protection in TN-C networks
