Doepke 09932304 RCBO for mixed frequency bands

RCBO combines earth leakage and circuit breaker in one device (FI-/LS-combination). They protect people from residual currents and systems against short-circuits and overload. The switches of the DRCBO 3 series function independent of mains voltage and are characterized by a high rated switching capacity. Separate displays provide a quick overview of the current operating status. DRCBO 3 is easy to install and remove. Type F switches are mix frequency sensitive. They protect against power supply independent of pulse and AC fault currents as well as residual currents with mixed frequencies differing from 50 Hz. They are surge current and weatherproof. Switches with the 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. Characteristics: Sensitive for alternating and pulsating DC fault currents of the mains frequency (type A) as well as alternating fault currents with mixed frequencies not equal to 50 Hz; small size for all rated currents; high short-circuit resistance; green-red contact position display; fault-current release display; bracket terminals with rear plug protection and wide terminal cross-section range for rail and cable wiring on both connecting sides; neutral right; tri-stable rest slider for easy installation and removal; Mounting type: Quick mounting on mounting rail; installation position in any way; feeding in any way; application areas: protection of electric circuits in residential and functional buildings as well as industrial systems with TN-S, TT and TN-C-S networks. In IT networks, FI/LS switches can be provided for shutdown in the event of a second ground fault; Ideal for single-phase frequency converters, systems with switched-mode power supplies and LED lighting systems; the use in plants with TN-C networks and for the protection of circuits is excluded. In which power electronics equipment can cause smooth DC fault currents or fault currents with frequencies not equal to 50/60 Hz.
