Residual current device DFS4 040-4/0,03-A EV

Residual current device DFS4 040-4/0,03-A EV – Doepke – 09134818 – 4014712215955: RCD DFS4 040-4/0.03-A EV number of poles 4, rated voltage 400V, rated current 40A, rated residual current 30mA, rated insulation voltage Ui 400V, rated impulse withstand voltage Uimp 4kV, mounting type DIN rail, residual current type A, short-circuit strength (Icw) 10kA, Surge current resistance 3kA, frequency 50 Hz, additional equipment possible, degree of protection (IP) IP20, width in pitch units 4, installation depth 69mm, ambient temperature during operation -25...40°C, degree of pollution 2, connectable conductor cross-section stranded 1.5...50mm² , Connectable conductor cross-section solid 1.5... 50mm², Residual current circuit breakers (RCCB) switch off the power supply if dangerously high residual currents occur. They protect people, animals and systems. DFS 4 are two- or four-pole residual current circuit breakers for one- or three-phase networks. In the standard version, the compact devices are four width units wide. They are available with many different fault current types and versions with rated currents of up to 125 A. The large two-tier terminals can also accommodate large conductor cross-sections. The released position of the multifunction shift knob makes troubleshooting easier. The free label software helps with the labeling. Type A switches are pulse and AC sensitive. This function is independent of the mains voltage. Switches in the EV design are intended for use in charging devices for electric vehicles. They have an additional function for detecting smooth DC residual currents >= 6 mA. In this way, they protect upstream residual current circuit breakers of type A or F against functional failures. Properties: mains voltage-dependent additional function for detecting smooth DC residual currents, tripping threshold of 6 mA for smooth DC residual currents, LED display for additional function operation, no additional wiring effort, VDE-certified, mains and auxiliary voltage-independent tripping, sensitive to alternating and pulsating DC residual currents (type A) small size for all rated currents, high short-circuit strength, two-tier terminals on both sides for large conductor cross-sections and busbar connections, switch position indicator, viewing window for labels, multifunction toggle switch with three positions: ''on'', ''off'', ''triggered'', also in the '' version HD'' available, connection C1 neutral conductor position on the left, also available as N on the right at no extra charge. Type of installation: quick attachment to DIN rail, any installation position, any feed direction, areas of application: These RCCBs are intended exclusively for use in facilities for charging electric vehicles. Use to protect systems is excluded. in which electronic equipment can cause fault currents with frequencies not equal to 50 Hz. All-current-sensitive residual current circuit breakers of type B or B+ are to be used here.
