Residual Current Devices
Specifications | Residual Current Devices FRCdM - digital, Type B and B+
Description
• Residual current devices, all-current sensitive
• Shape compatible with and suitable for standard busbar connec-
tion to other devices of the xEffect-series
• Twin-purpose terminal (lift/open-mouthed) above and below
• Busbar positioning optionally above or below
• Free terminal space despite installed busbar
• Universal tripping signal switch, also suitable for FAZ, FRBmM-1N
can be mounted subsequently
• Auxiliary switch Z-HK can be mounted subsequently
• Contact position indicator red - green
• Tripping indicator white - blue
• Additional Safety
- possibility to seal
- possibility to lock in ON and OFF position
• Delayed types (G, S) suitable for being used with standard fluores-
cent tubes with or without electronical ballast (30mA-RCD: 30 units
per phase conductor, 100mA-RCD: 90 units per phase conductor).
Notes: Depending of the fluorescent lamp ballast manufacturer
partly more possible. Symmetrical allocation of the fluorescent
lamp ballasts on all phases favourably. Shifting references of the
fluorescent lamp ballast manufacturer consider.
• The device functions irrespective of the position of installation
• Tripping is line voltage-independent. Consequently, the RCD is suit-
able for “fault current/residual current protection” and “additional
protection” within the meaning of the applicable installation rules.
• The 4-pole device can also be used for 3-pole connection:
See connection possibilities.
• The 4-pole device can also be used for 2-pole connection:
See connection possibilities.
• The test key “T” must be pressed every year. The system operator
must be informed of this obligation and his responsibility in a way
that can be proven. The yearly test interval is only valid for residen-
tial and similar applications. Under all other conditions (e.g. damp -
ly or dusty environment), it's recommended to test in shorter inter-
vals (e.g. monthly). A test is further needed if red and yellow LED
are flashing alternately.
• Pressing the test key “T” serves the only purpose of function test-
ing the residual current device (RCD). This test does not make
earthing resistance measurement (R
E
), or proper checking of the
earth conductor condition redundant, which must be performed
separately.
• Functioning
- The green LED becomes active at 0-30% I
Δn
- The yellow LED becomes active at 30-50% I
Δn
- The red LED becomes active at >50% I

• Potential-free auxiliary switch for use in control circuits, insulated
from main circuit of the switch gear according to IEC/EN60664
(0.25A ohmic load / 240V AC) in parallel with the yellow LED, for
external prewarning function. Bistabile, means the warning stays
on also when the breaker trips, until reset.
• Type -G/B and G/B+: High reliability against unwanted tripping.
Compulsory for any circuit where personal injury or damage to
property may occur in case of unwanted tripping (ÖVE/ÖNORM
E 8001-1 § 12.1.6).
Protection against all types of fault currents.
• Type -S/B and S/B+: Selective residual current device.
Protection against all types of fault currents.
• Type -S/Bfq: Suitable for speed-controlled drives with frequency
converters inhousehold, trade, and industry.Unwanted tripping is
avoided thanks to a tripping characteristic designedparticularly for
frequency converters.
Protection against all types of fault currents.
