Spring Cage Feed-Through Terminal Blocks ST
The product family ST with the new spring cage system "mini spring" is extremely space-saving. Space is saved thanks to a clearly smaller spring system without having to give up such familiar quality features as the large insertion space. The outstanding feature of the feed-through terminals is their space-saving design, the generous labeling options and a flexible bridging system. The insertion space of the ST terminal blocks is designed in such a way that flexible conductors with the rated cross section with ferrule can also be wired up without difficulty. The ground terminal blocks with the same shape as the feed-through terminal blocks make contact via simple snapping on the mounting rail and thus take over the ground conductor function. The housings are made of unbreakable polyamide 6.6 of the inflammability class V0 acc. to UL 94.

The ST series is ideally suited to these requirements.

Plug-in bridging system FBS The ST terminal block has dual channels for handling all types of bridging possibilities. By means of plug-in bridges the chain bridging can be achieved either with a 2-pos. standard jumper or with multi-position bridges. The multi-position version is especially useful
for fast bridging of multi-position terminal strips. The bridging between non-adjacent terminals can also be handled with this version. The plug-in bridges are

Frequently Asked Questions
What are the connection capacity requirements for solid stranded conductors?
The ST series supports a range from 0.08 to 1.5 mm2 (or 2.5 to 35 mm2 for ground blocks).
How can I bridge connections between non-adjacent terminals?
Use the multi-position plug-in bridge system, which supports bridging across various non-adjacent terminal positions.
What material is used for the housing and what safety standard does it meet?
The housings are made of unbreakable polyamide 6.6 and have an inflammability class V0 according to UL 94.
