Description: Residual current operated circuit-breaker with integral overcurrent protection, one-pole+N, 4 A, 0,03 A, C-Characteristic, Type A
Function: RCBOs combine residual current and miniature circuit-breakers in a single device (RCBO). They protect people against residual currents and systems against short-circuit and overload. Switches from series DRCBO 3 are independent of the mains voltage and have a high rated switching capacity. Separate displays enable a quick overview of the current operating conditions. DRCBO 3 can be conveniently installed and removed. Type A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage.Type A residual current circuit-breakers are sensitive to pulsating and alternating currents. This function is independent of the mains voltage. Switches with tripping characteristic C are optimised for electric circuits with high inrush or peak currents. Standard switches are designed for electric circuits with a rated voltage of 230 V or 400 V and a rated frequency of 50 Hz.
Properties: tripping not dependent on mains and auxiliary voltage, sensitive to AC residual currents and pulsating DC residual currents (type A), compact design for all rated currents, high short-circuit resistance, green/red switching position indicator, residual current tripping indicator, Strain-relief clamps with protection against wires being lodged behind them and wide terminal cross-section range for rail and line wiring on both connection sides, Use of conventional wiring rails possible, Neutral conductor right, tri-stable snap-in slider for easy mounting and removal, high electromagnetic compatibility (immunity to interference for industrial applications)
Installation: quick fastening to mounting rail, any installation position, supply as desired
Applications: Protection of circuits in residential and purpose-built buildings as well as industrial facilities with TN-S and TN-C-S networks. In IT networks, the RCCB/MCBs can be set to switch off in the event of a second earth fault, Not permitted for use in systems with TN-C networks; not permitted for protecting circuits in which the power electronics equipment may cause smooth DC residual currents or residual currents with frequencies not equal to 50/60 Hz.
