Protective Devices
Residual Current Devices PF6
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., Z-A. can be
mounted subsequently
Auxiliary switch Z-HK can be mounted subsequently
Contact position indicator red - green
Suitable for being used with standard fluorescent tubes with or without
electronical ballast (typically up to 20 units per phase conductor)
The device functions irrespective of the position of installation
Mains connection at either side
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.

RCD PF6 in a Three-Phase AC Network without Neutral Conductor
The N-terminal must be connected by a cable link
with the phase L2 (or L1), so that the test loop is
supplied with current and the RCD is tested cor-
rectly.
