Weidmuller TBs shape up to shake out

Electronics CELThe seismic testing is conducted to determine if products are capable of maintaining 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.
The approvals for thermal aging and seismic qualification for cabinet-mounted instrumentation and control equipment are in accordance with AECL Technical specification 98-68000-TS-011 Rev.1, and AECL technical specification 87-30000-TS-005.
