SEISMIC TERMINAL BLOCKSSeveral families of Weidmuller DIN-rail mounted terminal blocks, including W (screw clamp), KDKS (screw clamp fuse terminal), P (Push In connection), Z (tension clamp) and AKZ (TS15 screw clamp) series, have been seismic qualified. The terminal blocks can maintain specified performance requirements before, during and following a Design Basis Earthquake (DBE). The test for thermal aging determines if the product can withstand temperatures of 38 °C for a minimum of 40 years. The new approvals apply to Weidmuller DIN-rail mounted terminal blocks that feature housings made from Wemid, which has a UL 94 V-0 flammability rating. This includes Weidmuller's screw clamp, tension clamp and Push-in technology terminal blocks that are DIN-rail mountable on TS 35 rail. In addition, a selected group of TS 15 DIN-rail mount screw clamp terminal blocks have received the new seismic approvals.
