Weidmuller introduced its WGK Series of through-panel terminal blocks that provide a universal system for industrial control power filtering and UPS systems such as frequency converters and power supplies. The terminal blocks feature housing halves that interlock and enable an easy-to-mount through-panel termination system. In addition to the standard versions with vertical or horizontal wire entry, there is also a line of terminals that incorporate cable-lug termination for the panel interior. These feature self-locking screw clamp connection technology for a maintenance-free and vibration-proof connection. The terminal blocks are available to accommodate the UL-rated wire size range of AWG #30 to #4/0 (4 mm2 to 95 mm2). All versions offer touch-safe housings which incorporate dimpled interlocking points that are used to gang like terminals.
