Protective Devices
Residual Current Relays PFR., Core Balance Transformers Z-WFR.
• Residual current relays
• Shape compatible with and suitable for standard busbar connection to
other devices of the P-series
• Universal tripping signal switch, also suitable for PLS., PKN., Z-A. can be
mounted subsequently
• Auxiliary switch Z-HK can be mounted subsequently
• Contact position indicator red - green
• Delayed types 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 test key “T” must be pressed every month. The system operator must
be informed of this obligation and his responsibility in a way that can be
proven (self-adhesive RCD-label enclosed)
• Type -U: Suitable for speed-controlled drives with frequency converters in
household, trade, and industry.
Unwanted tripping is avoided thanks to a tripping characteristic designed
particularly for frequency converters.
