DISJUNTOR DIFERENCIAL DFS 4 040-4/0,03-A EV R HD

RCCB DFS 4 040-4/0,03-A EV R HD

Description
Residual current circuit-breakers, four-pole, 40 A, 0,03 A, Type A, for electromobility, N right, HD

Function
Residual current circuit-breakers (RCCB) switch the power supply off if dangerous high residual currents occur. DFS 4 are two-terminal or two-terminal pair residual current circuit-breakers for single- or three-phase networks. In the standard design, the compact devices are just four module widths wide. They are available with many different residual current types and variants for rated currents up to 125 A. The large two-tier terminals can also accommodate large conductor cross-sections. The trip position of the multi-function toggle switch simplifies fault-finding. The free label software helps in the labelling process. Type A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage. Switches in the EV design are intended for use in charging equipment for electric vehicles. They have an additional function to detect smooth DC residual currents = 6 mA. This retains the protective function of upstream residual current circuit-breakers of type A or F. With an airtight, encapsulated tripping mechanism from a special alloy and the stainless steel latch, residual current circuit-breakers in HD design are protected, in particular from corrosion, corrosive gases, moisture and extreme temperature fluctuations.

Properties
additional mains-voltage-dependent function for detecting smooth DC residual currents, Tripping threshold of 6 mA for smooth DC residual currents , 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, double-sided two-tier terminals for large conductor cross-section and busbar, switch position indicator, viewing window for labels, multifunction switch toggle with three positions: inchoninch, inchoffinch and inchtrippedinch, Neutral conductor position right

Instalation
quick fastening to mounting rail, any installation position, supply from any direction

Applications
These RCCBs are only designed for use in charging stations for electric vehicles, Not permitted for protecting systems in which electronic equipment may cause residual currents with frequencies not equal to 50 Hz. AC/DC sensitive residual current circuit-breakers of type B or B+ must be used in this case.
