Product FAQs
8 answersWhat does the E20 suffix indicate on the DLL36600E20?
The E20 designates an advanced electronic trip unit with adjustable long-time and short-time (LS) protection. This allows for superior coordination and precise trip settings compared to standard thermal-magnetic breakers.
What wire sizes are accepted by the terminals on the DLL36600E20?
The factory-installed line and load lugs accept two aluminum or copper conductors per phase, ranging from 2/0 AWG to 500 kcmil.
How does the DLL36600E20 mount inside an enclosure?
This is a unit-mount, feed-thru circuit breaker. It bolts directly to the backpan of Square D PowerPacT D-Frame enclosures or switchboards, rather than plugging into an I-Line bus.
Is the PowerPacT D-Frame DLL36600E20 a current-limiting breaker?
Yes, this breaker features a current-limiting design that provides robust short-circuit defense and helps protect downstream electrical equipment from severe fault currents.
What is the difference between the DLL36600E20 and the DJL36600E20?
While both are 600A, 3-pole PowerPacT D-Frame breakers with electronic trip units, they differ in their interrupting capacity. The DLL series provides a higher interrupting rating of 100kA at 480V, compared to the 65kA at 480V rating of the DJL series.
Is the Square D DLL36600E20 still the current model for new installations?
The PowerPacT D-Frame is a legacy series primarily used for replacements in existing switchboards. For modern upgrades and new panel builds, Square D has transitioned to the PowerPacT L-Frame series.
Does the DLL36600E20 trip unit utilize True RMS sensing?
Yes, the electronic trip unit features True RMS sensing, which ensures accurate overcurrent protection even in environments with high harmonic distortion from non-linear loads.
Is the DLL36600E20 suitable for HVAC applications?
Yes, this circuit breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment.
