Doepke FI/LS combination

RCBOs combine residual current and circuit breakers in one device (RCCB/MCB combination). They protect people from fault currents and installations from short circuits and overloads. The DRCBO 4 has a rated breaking capacity of 6 kA. In addition to a tripped indicator, it also features a labeling window. Type A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage. Switches with characteristic C are optimized for circuits with high inrush or peak currents. Standard switches are designed for circuits with a rated voltage of 230 V or 400 V and a rated frequency of 50 Hz.

Features:

• Pulsating and alternating current sensitive
• Mains voltage independent tripping
• Compact size for all rated currents
• Switching position indicator
• Separate indication of the tripping reason
• Terminal blocks with wide clamping cross-section range on both connection sides
• Neutral conductor on the right
• Labeling window
• Mounting type: Quick fastening on mounting rail
• Installation position arbitrary
• Supply connection arbitrary

Applications: Protection of circuits in residential and commercial buildings as well as industrial plants with TN-S, TT, and TN-C-S networks. In IT networks, RCCB/MCB switches can be provided for disconnection in the event of a second earth fault. The use in systems with TN-C networks and for the protection of circuits where power electronics equipment can cause smooth DC fault currents or fault currents with frequencies other than 50/60 Hz is excluded.
