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

Doepke FI / 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 NK characteristic offer the classic fire protection of 300 mA at frequencies up to 150 kHz. They are optimized for fire-prone operations. 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; The RCBO of type B + and type B with NK characteristics shall be used there. where fire protection is 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.
