Hager residual current circuit breaker CNA440D – 4-pole, 40 A, 100 mA, type S selective, 6 kA
The Hager CNA440D residual current circuit breaker is a 4-pole residual current device for electrical distribution systems.
It is designed as a type S selective and is selective with respect to downstream devices with lower rated residual current.
The residual current device (RCD) operates according to EN 61008-1 and EN 61008-2-1 and complies with VDE 0664 Part 10 and 11.
Thanks to the IP2x touch protection, safe installation is possible, while operation remains straightforward.
