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

• 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.
