Both DIN-rail and panel mounting is possible with the GPA line of high-current terminal blocks from Automation Systems Interconnect. The terminal blocks handle wire ranging in size from 2/0 to 500 thousand circular mils (MCM) with a rated voltage of 1000 V and current-handling capacity up to 415 A. The GPA series mounts on various DIN rails and features a locking mechanism. The GPA/FIX is a specific panel-mount terminal block that uses two mounting flanges to directly mount to equipment, while the GPA.70 block can accept a center jumper for connecting circuits together. In addition, a threaded locking rod can be inserted through the terminal blocks to hold them together.
