Protective Devices
Residual Current Devices PFDM
• Residual current devices
• Tripping is line voltage-independent. Consequently, the RCD is suitable for
the protection of humans and additional protection (ÖVE/ÖNORM E 8001-1
§ 6.1.2)
• Twin-purpose terminal (lift/open-mouthed) above and below
• Not busbar-compatible with other devices of the P-series
• Auxiliary switch Z-HD can be mounted subsequently
• Contact position indicator red - green
• 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 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)
• Type -A: Additionally protects against special forms of residual pulsating
DC which have not been smoothed.
• Type -S/A: Compulsory for systems with surge arresters downstream of
the RCD (ÖVE/ÖNORM E 8001-1 § 12.1.5).
