The 599-GP-02PSB is a 2-pole open-back terminal block designed for general industrial and commercial appliance wiring applications. It is rated for 15 A continuous current with listed ring lugs or unprepared copper wire (based on NEC Table 310-16, 75°C columns), and supports 150 V AC/DC under UL 1059 Class C (general industrial) or 300 V AC/DC under UL 1059 Class B (commercial appliances) with a short-circuit current rating of 10,000 A. The terminal block accommodates wire sizes #16 to #22 AWG with a binding screw torque of 9 in. lbs, features 3/8" center spacing, and has a maximum insulator base temperature of 150°C (302°F) per UL RTI. The connector eyelet is brass with nickel plating, and the insulator base is phenolic. This terminal block is commonly used in factory wiring, power distribution, and control panel applications where reliable multi-pole connections are required.
