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.
