Technical data

Combined RCD/MCB Devices PKPM3, 3-pole
• Combined RCD/MCB device
• Line voltage-independent tripping
• Compatible with standard busbar
• Twin-purpose terminal (lift/open-mouthed) above and below
• Busbar positioning optionally above or below
• Free terminal space despite installed busbar
• Guide for secure terminal connection
• Switching toggle in colour designating the rated current
• Contact position indicator red - green
• Fault current tripping indicator white - blue
• Comprehensive range of accessories suitable for subsequent installation
• Type -A: Protects against special forms of residual pulsating DC which
have have not been smoothed
• Typ -G: 10 ms time delay in order to avoid unwanted tripping
(e.g. during thunderstorms).
Compulsory in Austria for any circuit where personal injury or damage to
property may occur in case of unwanted tripping (§12.1.6 ÖVE/ÖNORM
E 8001-1).
