Product FAQs
6 answersWhat panelboards are compatible with the LX36225G circuit breaker?
This unit is designed specifically for use in Square D I-Line panelboards and switchboards. It features a plug-on line connection that attaches directly to the panelboard bus.
What protection functions are included in the LSIG trip unit?
The solid-state electronic trip unit provides adjustable Long-Time, Short-Time, Instantaneous, and Ground-Fault (LSIG) protection. This allows panel builders to finely coordinate the breaker's trip curve with other devices in the electrical system.
Does this breaker use traditional thermal-magnetic trip technology?
No, the LX36225G features an electronic Micrologic trip unit. This solid-state technology utilizes true RMS sensing to deliver more accurate and reliable response times during fault conditions compared to traditional thermal-magnetic mechanisms.
What wire configurations are supported by the load-side lugs?
The terminal lugs are dual-rated for both aluminum and copper conductors. They will safely accept either a single 1 AWG to 600 kcmil wire, or two 1 AWG to 250 kcmil wires per phase.
How does the I-Line mounting style benefit installation?
I-Line breakers feature integrated plug-on jaws on the line side that clamp securely onto the switchboard busbars. This design provides a reliable electrical connection, allows for rapid installation, and simplifies phase balancing compared to standard bolt-on configurations.
Is the Square D LX series a current production model?
The LX series is a legacy molded case circuit breaker frame. Finding direct LX replacements allows facilities to maintain and service their existing I-Line switchboards without the need for complex adapter kits or expensive panel upgrades.
