Residual Current Protective Devices / Arc Fault Detection Devices (AFDDs)
Introduction
SIGRES
SIGRES RCCBs were developed for use in harsh ambient con-
ditions, such as swimming baths as protection against chlorine
and ozone, in the agricultural sector (ammonia), on building
sites and in the chemical industry (nitrogen oxide, sulfur dioxide,
solvents), in the food processing industry (hydrogen sulfide) and
in unheated rooms (dampness). The patented active condensa-
tion protection requires a continuous power supply and bottom
infeed if the RCCB is switched off.
When used in ambient conditions as defined in product stan-
dard EN 61008-1, the operation interval for pressing the test
button can be extended to once a year.
Super resistant
æ
Super resistant (short-time delayed) RCCBs meet the maximum
permissible break times for instantaneous devices. However,
by implementing a short-time delay they prevent unnecessary
tripping operations, and thus plant faults, when pulse-shaped
leakage currents occur – as is the case when capacitors are
switched on.
Selective
î
Can be used as upstream group switch for selective tripping
contrary to downstream, instantaneous or short-time delayed
RCCBs.

devices, see the technology primer

5SV / 5SM3 RCCBs
Residual Current Protective Devices / Arc Fault Detection Devices (AFDDs)
■
Overview
RCCBs are used in all systems up to 240/415 V AC. Devices of
type AC trip in the event of sinusoidal AC residual currents, type
A also trips in the event of pulsating DC residual currents.
In addition, RCCBs type F also detect residual currents with
mixed frequencies up to 1 kHz.
RCCBs with a rated residual current of maximum 30 mA are
used for personnel, material and fire protection, as well as for
protection against direct contact. RCCBs with a rated residual
current of 10 mA are primarily used in areas that represent an
increased risk for personnel.
Since the introduction of DIN VDE 0100-410, all socket outlet
current circuits up to 20 A must also be fitted with residual
current protective devices with a rated residual current of
max. 30 mA. This also applies to outdoor electrical circuits
up to 32 A for the connection of portable equipment.
Devices with a rated residual current of maximum 300 mA are
used as preventive fire protection in case of insulation faults.
RCCBs with a rated residual current of 100 mA are primarily
used outside Europe.

Benefits
• Instantaneous RCCBs with the N connection on the left-hand
side enable simple bus mounting with standard pin busbars
with miniature circuit breakers installed on the right-hand side
• Instantaneous RCCBs with the N connection on the right-hand
side can be bus-mounted with miniature circuit breakers using
a special pin busbar
• Instantaneous type A devices have a surge current withstand
capability with current waveform 8/20 μs of more than 1 kA,
super resistant of more than 3 kA and selective of more than
5 kA. This ensures safe operation
• SIGRES has an extremely long service life due to a patented
active condensation protection and identical dimensions en-
able the quick and easy replacement of existing instanta-
neous RCCBs
• Super resistant devices increase system availability, as un-
necessary tripping is prevented in power supply systems with
short-time glitches
• Selective RCCBs increase system availability as a staggered
tripping time enables the selective tripping of RCCBs con-
nected in series in the event of a fault
• Auxiliary switches or remote controlled mechanisms are also
available as additional components
• The operating handle and the test button can be locked by
means of a handle locking device
• All additional components that match the 5SY and 5SL
miniature circuit breakers can also be fitted on the 5SV

Technical specifications
5SV3
1)
5SV residual current operated circuit breakers have been developed for
50 Hz systems and can detect and shut down ground fault currents of this
frequency, but in the case of residual currents that deviate markedly from
this frequency, or that have a higher proportion of harmonics, the trip
values increase slightly.

Configuration
When using residual current protective devices type F, please
note the following:
• They are not suitable for equipment that can generate smooth
DC residual currents (see Table, page 9, circuits 8 to 13).
• They are not suitable for installation in networks with frequen-
cies that deviate from the rated frequency (50 Hz) (not at the
outgoing terminal of a frequency converter).
• When configuring and setting up electrical systems with
type F, the same applies as for residual current protective
devices type A, i.e. electrical loads that can generate smooth
DC residual currents in the event of a fault are assigned their
own circuit with a universal current-sensitive residual current
protective device (type B or type B+).
It is not permitted to branch off electrical circuits with these types of
electrical loads downstream of pulse-current-sensitive residual current
protective devices (type A or type F).
