描述

The 1402303 is a power terminal block rated for 310 amperes at 600 volts AC/DC, designed for industrial factory and field wiring applications. It accommodates wire sizes from 350 kcmil to #6 AWG on both line and load sides, with a short-circuit current rating (SCCR) of 10,000 A and a CU7AL -75°C connector terminal rating suitable for both copper and aluminum wire. The terminal block features a phenolic insulator base with UL94V0 flammability rating, aluminum tin-plated connectors and terminal screws, and is compliant with UL 1059, CSA 22.2 No. 158 (wire classes B & C), and IEC 60947-7-1. It is RoHS compliant and operates across an insulator base temperature range of -40°C to +150°C (UL RTI). This terminal block is ideal for power distribution, motor control, and high-current switching applications in industrial control panels and electrical enclosures.
