Function
Residual current circuit-breakers (RCCBs) are components for implementing protective measure "Automatic disconnection of the powersupply" as corresponding international installation regulations. Series DGL2 devices are compact two or four-pole residual current circuit-breakers. In the standard design, they only take up four module width units of space. Although DGL2 devices for AC and pulsating DCresidual currents are actually designed for three-phase networks, they can also be used in single-phase networks.However, in addition tothese, special variants are also available for single or three-phase operation in the form of the AC/DC sensitive designs (type B, type B+).In spite of the compact dimensions, a number of different tripping currents and characteristics are available at rated currents, dependingon the design, up to 63 A.
Type A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage.Type A RCCB
are sensitive to pulsating and alternating currents. This function is independent of the mains voltage.► RCCB of series EV are also
fitted with an active mains-voltage-dependent function for detecting smooth DC residual currents and a tripping threshold of 6 mA. Thisprevents possible pre-magnetisation of an upstream type A or F residual current circuit-breaker due to a smooth DC residual current, sothat this circuit-breaker can continue fulfilling its protective function. They are only designed for use in charging columns or wall boxes forcharging electric vehicles. RCCBs in design EV must not be used in place of a type B or B+ residual current circuit-breaker.
Features
additional mains-voltage-dependent function for detecting smooth DC residual currents, Tripping threshold of 6 mA for smooth DCresidual currents , tripping not dependent on mains and auxiliary voltage, sensitive to AC residual currents and pulsating DC residualcurrents (type A), compact design for all rated currents, high short-circuit resistance.
Mounting
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 electronicequipment may cause residual currents with frequencies not equal to 50 Hz. AC/DC sensitive residual current circuit-breakers of type B orB+ must be used in this case.
