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.
