NSYEB power distribution blocks are enclosed IEC versions of our NEMA 9080 power distribution blocks, which are finger safe. The terminals of these power terminal blocks are finger safe from the front according to IP20. They are one pole modular units with an interlocking dovetail feature that enables ganging of the blocks to create multipole configurations according to application requirements. They have Short-Circuit Current Ratings (SCCR) up to 100 kA with fuses and circuit breakers. Refer to the catalog for details on this. The lugs in these blocks are available with either copper or aluminum. This block has a tin plated aluminum lug. The line side lug of this block is rated to 760A at 600 V when copper wire is used and 620A at 600 V when aluminum wire is used. Each of the two line side terminals will accept 4 AWG to 500 kcmil copper or aluminum wires. Each of the eight load side terminals will accept 14 to 2/0 AWG copper wire or 6 to 2/0 aluminum wires. This block can be mounted directly to a panel. This block is 4.63 inches tall, 2.61 inches wide and 3.35 inches deep. This block is UL Listed, CSA cerified and RoHS compliant.
