IDC Terminal Blocks Hold Fast To Wires

With a pullout force of at least a 50 lb. for 14 AWG wire, the taris series of insulation displacement (IDC) terminal blocks are said to meet or exceed UL 486A standards for wire retention. The standards are the same ones applied to screw-clamp and spring-clamp terminal blocks.
The new IDC terminal blocks employ a proprietary clamping design that moves the clamping mechanism to the wire with 80 to 100 Newtons of contact force. The blocks are available in 29 versions that include single-double feed-through, knife-edge disconnect, fuse, and ground blocks. All blocks in the series are fitted with universal DIN-rail mounting feet.
