Protective Devices
Residual Current Devices PF7
• Residual current devices
• 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 PL., PFL., 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 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 the meaning of the applicable installation rules
• Mains connection at either side
• Types with 80 a 100 A permissible short-circuit back-up fuse (PF7-80,
PF7-100): Take into account overload protection
• The 4-pole device can also be used for 3-pole connection.
For this purpose use terminals 1-2, 3-4, and 5-6 (+ cable link).
• The 4-pole device can also be used for 2-pole connection.
For this purpose use terminals 5-6 and N-N.
• 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)
• 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.
• Type -A: Protects against special forms of residual pulsating DC which
have have not been smoothed
• Type -G: High reliability against unwanted tripping. Compulsory for any cir-
cuit where personal injury or damage to property may occur in case of
unwanted tripping (ÖVE/ÖNORM E 8001-1 § 12.1.6).
• Type -G/A: Additionally protects against special forms of residual pulsating
DC which have not been smoothed.
Special types for X-ray application PF7-...-R
• Type -S: Selective residual current device sensitive to AC, type -S.
Compulsory for systems with surge arresters downstream of the RCD
(ÖVE/ÖNORM E 8001-1 § 12.1.5).
• Type -S/A: Additionally protects against special forms of residual pulsating
pulsating DC which have not been smoothed.
