Product FAQs
7 answersWhat type of trip unit is installed in the DJL36400E20?
The E20 suffix indicates this breaker is equipped with a Micrologic 2.0 electronic trip unit. It provides adjustable long-time and short-time (LS) protection.
Can the DJL36400E20 be reverse fed?
Yes. PowerPacT D-frame circuit breakers, including those with electronic trip units like this model, are suitable for reverse feeding. Always verify specific equipment labeling before installation.
Can I install this breaker in a Square D I-Line panelboard?
No. The DJL36400E20 is a unit-mount breaker designed for switchboards, motor control centers, and individual enclosures. For an I-Line panelboard, you need an I-Line mounting version, such as the DJA36400E20.
Does the DJL36400E20 provide ground fault protection?
No. The Micrologic 2.0 trip unit only provides long-time and short-time (LS) protection. If ground fault equipment protection is required, you need a breaker with a Micrologic 6.0 (LSIG) trip unit, indicated by an E60 suffix.
What does the J in the DJL36400E20 part number signify?
In the PowerPacT D-frame series, the J designates the interrupting capacity tier. It indicates a high interrupting rating of 65 kA at 480 VAC.
What is the wire capacity for the standard lugs on this 400A breaker?
The standard lugs accept two 2/0 AWG to 500 kcmil aluminum or copper conductors per phase, allowing for parallel conductor installations.
What is the modern replacement for the legacy DJL36400E20?
The PowerPacT D-frame has been replaced by the PowerPacT L-frame series. The modern equivalent for this 400A unit-mount breaker is the LJL36400U31X.
