The 1331588CH is a distribution power block designed for industrial power distribution and field wiring applications at 600 V AC/DC. It accommodates line-side wire from 600 kcmil to #2 AWG and load-side wire from 1/0 to #14 AWG, with a rated current capacity of 420 A for copper wire and 340 A for aluminum wire based on NEC Table 310-16 at 75°C. The terminal block features a high-conductivity aluminum connector with tin plating, a glass-filled polycarbonate insulator base and hinged cover rated for UL 94 V-0 flammability, and is approved for UL 1059 Class C general industrial use with a maximum insulator temperature of 125°C. Short-circuit current ratings reach 100,000 RMS symmetrical amps depending on wire size and overcurrent protection class, making it suitable for demanding industrial power distribution, panel mounting, and factory/field wiring installations.
