DIN rail terminal blocks
By Mary Del
Oct. 20, 2014 – Wieland Electric Inc. says it has significantly enhanced the design of its DIN rail mounted screw-clamp terminal blocks. Part of the company’s selos family, the WT Series terminal blocks feature an enhanced push-in jumpering system that forms a low-resistance, vibration-proof connection when inserted. This is achieved by separating the rugged steel spring for mechanical fastening from the jumper’s copper current bar. The dual-channel jumpering system enables extended jumper lengths, as well as the ability to bridge multiple potentials on parallel blocks (e.g., linking alternate terminals, such as every second or third block, using notched jumpers). Another new feature of the WT Series terminal blocks is the introduction of screwless (snap-on) ground blocks to speed up installation onto DIN rails. In addition, the redesigned terminal blocks now come in a uniform size up for wires up to six AWG. The WT Series terminal blocks now have the option of using a flexible terminal marking system using commercially available thermal transfer labels. Wieland’s standard hard plastic marking tags are also available for applications requiring a non-sliding, robustly anchored tag.
