Description
Built for commercial power distribution, the Square D LEL36300LI is a 3-pole, 300A molded case circuit breaker. It features true RMS sensing for accurate response times in demanding environments. This unit-mount breaker fits into Square D QED switchboards, Model 6 MCCs, and individual enclosures. When upgrading, this legacy L-Frame unit is replaced by the LJL36400U31X. It provides a 65 kAIC rating at 480VAC and includes adjustable long-time and instantaneous (LI) trip functions.Specifications
