Doepke 09932115 DRCBO 3 B20/0.3/1N-A /RCBO FI/LS combination

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 A switches are sensitive to pulse and alternating current. This function is independent of the mains voltage. Switches with tripping characteristic 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: tripping independent of auxiliary voltage, sensitive for alternating and pulsating direct residual currents (type A), 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. Use in systems with TN-C networks and for protecting circuits in which power electronics equipment can cause smooth direct residual currents or residual currents with frequencies other than 50/60 Hz is excluded.
