DRCBO 4 B20 / 0.03 / 3N-B SK, Doepke F- / LS combination 3p + N, 20 A, 0.03 A, B-Char.Type B, KV

RCBO combines error current and control switch in one device (FI / LS combination). They protect people from flaws and systems from short circuit and overload. DRCBO 4 has a rated power of 6 kA. In addition to the triggered display, they also offer a label window. Type B switches are all-current sensitive at frequencies from 0 Hz (smooth DC) to 150 kHz. They are increased shock current and maternal. Switches with the SK characteristic stand for error protection and high plant availability. They are characterised by a lower response sensitivity at higher frequencies. Investment-related missolutions are thus avoided as far as possible. The SK characteristic is optimized for plants where no fire protection is required. Switches with the trigger characteristic B are the standard protection for light and socket circuits. Standard switches are for circuits with a measurement voltage of 230 V or 400 V and a rated frequency of 50 Hz. Characteristics: all-current sensitive to error flows with frequencies from 0 Hz (smooth direct current) to 150 kHz; power-independent trigger for type A error flows; low size for all measurement flows; position display; separate display of the ground of action; Tensile terminals with a wide range of terminal cross-section on both sides of the connection; Neutral ladder on the right; the label window; Type of assembly: quick fitting on the support rail; any installation position; feed-in preferably from above; Applications: commercial and industrial installations with TT, TNS and TNC systems in which power electronics are used without galvanic power separation, such as frequency converters, switching power supplies, high-frequency current converters, photovoltaic or USB systems with trafolous inverters; RCBO with SK-characteristic can be used there. where high flow flows are expected and fire protection is not required; Note: suitable for use in 50-Hz AC networks; RCBO is also available on request for other frequencies; not for use in direct current networks and on the output side of controlled electrical equipment such as frequency converters.
