描述

The 1403404 is a power terminal block designed for high-current industrial power distribution applications, rated for 310 amps at 600 volts AC/DC. It accommodates line-side conductors from 350 kcmil to #6 AWG and load-side conductors from #4 to #14 AWG, with a connector terminal rating of 75°C for both copper and aluminum wire. The block features a phenolic insulator base with UL94V0 flammability rating and operates across a temperature range of -40°C to +150°C (UL RTI). It is UL recognized (UL 1059, File No. XCFR2.E62806), CSA certified (C22.2 No. 158), and CE compliant to IEC 60947-7-1, with short circuit current ratings up to 100,000 A RMS symmetrical at 600V depending on conductor and fuse class combinations. This terminal block is ideal for power distribution panels, motor control centers, and industrial switchgear where reliable high-current connections and multi-wire termination are required.
