Specifications
Product FAQs
7 answersWhat type of panelboards accept the ME36400LI circuit breaker?
The ME36400LI is designed specifically for Square D I-Line panelboards and switchboards. Its plug-on jaw construction connects directly to the I-Line bus assembly.
What do the LI trip functions on the ME36400LI indicate?
The LI designation indicates that the Micrologic electronic trip unit provides adjustable Long-Time (L) and Instantaneous (I) protection. It does not include Short-Time or Ground Fault trip functions.
How is the line side of the ME36400LI connected during installation?
The line side utilizes the I-Line plug-on connection, which engages directly with the panelboard busbars. Only the load side requires mechanical lug connections for the outgoing conductors.
Is the ME36400LI a legacy circuit breaker?
Yes, the ME36400LI is part of the legacy Square D M-Frame series. It is often sourced as a direct replacement for existing I-Line panelboards that utilize older ME, MX, or MA frame breakers.
What is the benefit of the solid state trip unit in the ME36400LI?
The solid state Micrologic trip unit provides more precise and repeatable trip curves compared to traditional thermal-magnetic breakers, enhancing overall system coordination and electrical safety.
Can the ME36400LI be used in a standard unit-mount enclosure?
No, this specific catalog number features an I-Line plug-in connection. It cannot be bolted directly to a backpan or used in a standard unit-mount enclosure without the proper I-Line bus structure.
What does the ME prefix in the ME36400LI catalog number mean?
The ME prefix designates it as a Square D M-Frame circuit breaker equipped with a solid state electronic trip unit, specifically configured for I-Line panelboard mounting.
