描述

The 1423574 is a power terminal block rated for 175 A at 600 V AC/DC, designed for industrial electrical distribution and load switching in control panels and enclosures. It features a phenolic insulator base with UL94V0 flammability rating and operates across a temperature range of -40°C to +150°C (UL RTI). The line side accepts wire sizes from 2/0 to #14 AWG (copper stranded or solid), while the load side uses 1/4-20 stud terminations with listed compression/crimp lugs or ring terminals. The connector is constructed from aluminum with tin plating, and terminal screws are steel with nickel plating, ensuring corrosion resistance and reliable electrical contact. It is UL recognized (UL 1059), CSA certified (C22.2 No. 158), and CE compliant to IEC 60947-7-1, with a default short circuit current rating (SCCR) of 10,000 A and capability to achieve up to 100,000 A SCCR with appropriate fusing and conductor combinations. This terminal block is ideal for power distribution, motor control, and industrial automation systems requiring robust, code-compliant electrical connections.
