Protective Devices
Residual Current Devices dRCM - digital, types B and B+
Residual current devices, all-current sensitive
Shape compatible with and suitable for standard busbar connection to
other devices of the P-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 PLS., PKN., ZP-A. 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 fluorescent
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 man-
ufacturer consider.
The device functions irrespective of the position of installation
Tripping is line voltage-independent. Consequently, the RCD is suitable for
“fault current/residual current protection” and “additional protection” with-
in 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 residential and similar
applications. Under all other conditions (e.g. damply or dusty environ-
ment), it's recommended to test in shorter intervals (e.g. monthly).
A test is further needed if red and yellow LED are on together.
Pressing the test key “T” serves the only purpose of function testing 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
Δn
Potential-free relay (NO contact, in parallel with the yellow LED, up to 1 A
ohmic load / 230 V~) for external prewarning function. Bistabile, means the
warning stays on also when the breaker trips, until reset.
Type -G/B und 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 und S/B+: Selective residual current device. Protection against
all types of fault currents.
