FlexLine® highlights

Speed up installation thanks to our push-in technology.

Stay flexible with our flex terminals.

Save space through slim design.

Enjoy convenient installation from the front.

Speed up installation and save up to 50% on time with our push-in technology. Simply insert the cable by pushing horizontally against the opening of the load-side push-in terminal without the need for a screwdriver or any tools. The force of the spring keeps the pressure on the cable at a constant level, eliminating the need to tighten them after installation, as required by most wiring regulations.

And thanks to its push-in busbar terminals, FlexLine® busbars can be installed in a quick and time-saving way as well.

Keeping things simple, we've opted for a one-size-fits-all approach to mounting busbars. Whenever the neutral terminals are not required, our flex terminals accommodate this busbar pin without any mechanical or electrical connection.

Both the devices as well as the busbar can be supplied with cable via a dedicated screw terminal. The screw terminal is designed to allow rigid, flexible cables and flexible cables with ferrules.

All FlexLine® protection devices can be flexibly combined with only one busbar, as the phase sequence is always the same. This significantly reduces the stockkeeping.

More and more devices need to fit into one enclosure as selectivity and building automation requirements increase. With this in mind, FlexLine® has been developed to save up to 50% on the space in the consumer unit.

The FlexLine® range does not only save space due to its slim design, the double-slot terminals also allow the devices as well as the the busbar to be supplied without a feed-in module. This screw-terminal is designed in such a way that rigid, flexible cables with or without ferrules can be inserted.

Additionally, FlexLine® protection devices can be flexibly combined with one busbar in only one row thanks to their flex terminals, saving even more space.

For the smoothest installation process possible, all load-side terminals on the top have been positioned in such a way that allows horizontal cable insertion. No need to squeeze your fingers into the small gap between the rows to insert a cable - now enjoy convenient installation with more space for wiring.
