Product FAQs
6 answersHow does the LDA36600U33X connect to the panelboard?
This breaker features an I-Line plug-on connection for the line side and mechanical lugs on the load side. It is designed to snap directly into Square D I-Line panelboards and switchboards, which helps reduce installation time.
What type of trip unit is included with the LDA36600U33X?
It comes equipped with a Micrologic 3.3S electronic trip unit. This solid state system provides adjustable Long-Time, Short-Time, and Instantaneous (LSI) protection, allowing for precise selective coordination in complex electrical systems.
What wire sizes are compatible with the load side lugs on this 600A breaker?
The factory-installed load lugs accept two conductors per phase, ranging from 2/0 AWG to 500 kcmil. They are rated for both aluminum and copper wire.
Is the LDA36600U33X rated for 80 percent or 100 percent continuous current?
This PowerPacT L-frame breaker has a standard 80 percent continuous current rating.
Can I use this breaker in place of older Square D L-frame breakers?
Yes, the PowerPacT LDA36600U33X is designed to fit into the same I-Line panelboard spaces as legacy Square D L-frame breakers, making it a direct upgrade for older 600A installations.
Why is the Short-Time trip function important on this breaker?
The Short-Time adjustment on the Micrologic 3.3S trip unit allows the breaker to delay tripping during a minor short circuit. This delay gives downstream breakers time to clear the fault, which prevents unnecessary power loss to the rest of the facility.
