Function
Residual current circuit-breakers (RCCBs) are components for implementing protective measure "Automatic switch-o of power supply"
as per VDE 0100 part 410 or corresponding international installation regulations. Series DFS 2 devices are compact two-pole residual
current circuit-breakers for single-phase networks. In the standard design, they only take up two module width units of space. In spite
of the compact dimensions, a number of dierent tripping currents and characteristics are available at rated currents, depending on the
design, up to 125 A. Usually the neutral conductor connection is located on the left side, but can be on the right if desired. Furthermore, all
devices are available in the "HD" design, which is especially suitable for use in extreme environments (tunnels, swimming pools, etc.) They
also have large two-tier terminals for large conductor cross-sections, a practical multifunctional switch toggle and can be provided with
pre-prepared labels using free-of-charge software. Switches with residual current characteristic A are independent of the mains voltage
and allow the detection of sinusoidal AC currents and pulsating DC residual currents. With the FT design the connections of the internal
test key are wired to two terminals in order to be able to activate the test device externally. An auxiliary contact also reports the switch-o
of the safety switch.
Features
integrated auxiliary switch function, contact data same as for DHi, The technical properties of the basic switch are not changed by the
FT option., 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 crosssection and busbar, switch position indicator, viewing window for labels, multifunction switch toggle with three positions: "on", "o" and
"tripped", , neutral conductor in standard design left, optionally available: N right for any four-pole device at no extra cost
Mounting
quick fastening to mounting rail, any installation position, supply from any direction
Applications
Power supplies to residential and purpose-built buildings as well as industrial facilities with TN-S, TT and TN-C-S networks. In IT networks,
the residual current circuit-breakers of this series can be set to switch o in the event of a second fault, RCCBs from the "FT" series are
especially suitable for the remote switch-o of systems and parts of systems and for being tripped by hazard alarms, amongst other
devices, Not permitted for use in TN-C networks; not permitted for protecting systems in which electronic equipment may cause smooth
DC residual currents or residual currents with frequencies not equal to 50 Hz. Comprehensive protection is not provided in this case. For
these applications we recommend our AC/DC sensitive residual current circuit-breakers (type B or B+).
Notes
Do not use as emergency stop circuit!, The contacts of the external command device must be designed for a rated residual current ≥ 0.5 A
and for the rated voltage of the residual current circuit-breaker.
