Doepke 09932306 DRCBO 3 B25/0.03/1N-F FI/LS switch

RCBOs combine residual current and circuit breakers in one device (FI/LS combination). They protect people from residual currents and systems from short circuits and overloads. The switches in the DRCBO 3 series work independently of the mains voltage and are characterized by a high rated switching capacity. Separate displays provide a quick overview of the current operating status. DRCBO 3s can be easily installed and removed. Type F switches are mixed frequency sensitive. They protect independently of the mains voltage against pulse and alternating residual currents as well as residual currents with mixed frequencies deviating from 50 Hz. They are resistant to increased surge currents and storms. Switches with tripping characteristics B are the standard protection for light and socket circuits. Standard switches are designed for circuits with a rated voltage of 230 V or 400 V and a rated frequency of 50 Hz. Properties: sensitive to alternating and pulsating direct residual currents of the mains frequency (type A) as well as alternating residual currents with mixed frequencies not equal to 50 Hz, small size for all rated currents, high short-circuit strength, green-red contact position indicator, residual current trip indicator, clamping yoke terminals with rear plug protection and wide clamping cross-section range for rail and cable wiring on both connection sides, neutral conductor on the right, tristable locking slides for easy installation and removal, mounting type: quick attachment to mounting rail, installation position as desired, feed-in as desired, areas of application: protection of circuits in residential and commercial buildings as well as industrial plants with TN-S, TT and TN-CS networks. In IT networks, FI/LS switches can be provided for shutdown in the event of a second earth fault, ideal for single-phase frequency converters, systems with switching power supplies and LED lighting systems, use in systems with TN-C networks and for protecting circuits is excluded. in which power electronics equipment can cause smooth DC fault currents or fault currents with frequencies other than 50/60 Hz.
