Residual Current Devices CFI6
• Residual current devices
• Tripping is line voltage-independent. Consequently, the RCD is suitable for
fault current/residual current protection and additional protection
(ÖVE/ÖNORM E 8001-1 § 6.1.2)
• Matching with CLS6, CLS4
• Shape compatible with and suitable for standard busbar connection to
other devices of the C-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 CLS., CKN., Z-A. can be
mounted subsequently
• Auxiliary switch Z-HK can be mounted subsequently
• Contact position indicator red - green (CFI6-4-pole)
• 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
• 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
• 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

RCD CFI6 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.
