Attachment plugs for the socket

Do you want to protect your sensitive devices? Then you need to implement type 3 device protection as the last protection stage. Important requirement: surge protection must already be installed in the sub-distribution.

Retrofitting into existing installations

Attachment plugs with integrated type 3 device protection  

Easy retrofitting with MAINTRAB attachment plugs

Type 3 device protection limits surges to levels that even sensitive termination devices can safely handle.

Installation is very easy: simply plug the MAINTRAB attachment plug into the socket and then the mains plug of the device to be protected into MAINTRAB. Optimum protection is then provided for all connected termination devices.

MAINTRAB with interface protection kills two birds with one stone:
you only need to connect one attachment plug in order to simultaneously protect the power supply and another interface against surge voltages.
