Description
Part of the legacy L-Frame series, this 600-amp molded case circuit breaker provides reliable thermal-magnetic protection for commercial and industrial applications. It installs into Square D switchboards, motor control centers, and compatible enclosures using standard bolt-on lug terminals. Rated for 65kAIC at 480VAC, the unit features adjustable magnetic trip settings and serves as a robust solution before transitioning to the newer LJL36600 retrofit alternatives.Specifications

Product FAQs
6 answersWhat equipment is the Square D LCP36600MT designed to fit?
This legacy L-Frame breaker is engineered for installation in Square D switchboards, motor control centers (MCCs), and compatible industrial enclosures requiring a 600A bolt-on main or feeder device.
Is there a modern retrofit alternative for the legacy LCP36600MT?
Yes. While the LCP36600MT remains a direct replacement for existing legacy L-Frame systems, facilities upgrading their panels often transition to the newer Square D PowerPact L-Frame series, such as the LJL36600. Always verify panel clearances and mounting hardware before retrofitting.
What is the conductor capacity for the LCP36600MT lugs?
The factory lugs are designed for dual-wire configurations, accepting two conductors per phase. They accommodate 2/0 AWG to 500 kcmil aluminum or copper (Al/Cu) wire, making it suitable for parallel runs in high-amperage industrial feeders.
How does the adjustable magnetic trip function on the LCP36600MT work?
The thermal-magnetic trip unit features a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection. This adjustability allows panel builders to coordinate the breaker's short-circuit response with downstream devices and specific motor loads.
Is the LCP36600MT rated for direct current (DC) systems?
Yes. In addition to its standard 240V, 480V, and 600V AC ratings, this breaker is UL listed for 250VDC applications, providing a 10kA interrupting capacity for DC distribution networks.
What safety certifications does the LCP36600MT hold?
This molded case circuit breaker is both UL listed and CSA certified, ensuring it meets strict North American safety standards for overcurrent and short-circuit protection in commercial and industrial environments.
