for cables with connecotrs / IP54 / UL Type 12

icotek cable entry frames with fire penetration seals, approved for use in railway technology (meeting the standards EN 45545-2, EN 45545-3 and EN 1363-1).

Split cable entry system for routing cables with connectors providing an IP54 / UL type 12 rating. Routing, sealing and providing strain relief for cable diameters from 1 to 35 mm. The cable entry system is easy to install. Cable grommets are placed into compartments and are securely fixed to the frame during assembly. 

The KEL-U-BS frame matches exactly the cut-out dimensions for 10-, 16- and 24-pin standard industrial connectors. The KEL-U-B-BS frame matches exactly the cut-out dimensions of 46 × 46 mm measuring instruments. The single-row version KEL-E-BS is particularly suited for flat connectors. The small frame is ideal for applications with limited space. A flat rubber gasket is included in the shipment.

The intumescent (foaming) IFPS fire penetration seals which are mounted at the backside of the cable entry components consist of expandable graphite and increase their volume by a multiple in case of a fire.

This creates a barrier which prevents a penetration of flames and high heat from one room into another for the longest possible period.
