Square D RKF36160U43A is a 3-pole molded case circuit breaker from the Powerpact family, designed for solid-state protection of industrial electrical systems. It is rated for 600V AC, 1600A continuous current, and delivers a 65kA interrupting capacity at 480V, with LSI (Long-Time, Short-Time, and Instantaneous) trip functions for precise overcurrent coordination. The unit measures 16.24 in (412.50 mm) in height, 16.54 in (420.12 mm) in width, and 14.49 in (368.05 mm) in depth, weighing 52.001 lb, with a bolt-on connection and support for AWG 3/0 to 750 kcmil aluminum or copper wire. It complies with UL, CSA, NEMA, NMX J-266, and IEC 60947-2 standards, with additional UL, CSA, and NOM certifications, making it suitable for 3-phase industrial applications requiring high fault current protection.
