Product FAQs
5 answersWhich metering centers are compatible with the DJM32400E20 circuit breaker?
This breaker is specifically designed to mount into Square D EZ Meter-Pak commercial metering centers, including EZML and EZMK series enclosures.
What is the modern replacement for the legacy DJM32400E20?
The DJM frame is a legacy product. Square D has replaced it with the PowerPact L-Frame series. The direct modern equivalent is catalog number LJM36400U31X, though the original DJM frame is often preferred for exact replacements in existing EZ Meter-Pak setups.
Can the trip curve on the DJM32400E20 be adjusted for specific load requirements?
Yes, it features an adjustable electronic solid-state trip unit. It includes adjustable trip functions, such as Long-Time and Short-Time settings, allowing panel builders to precisely coordinate the breaker with other protective devices in the system.
How are the line and load connections configured on this breaker?
The line side utilizes a bolt-on connection to securely attach directly to the EZ Meter-Pak buswork, while the load side is equipped with mechanical lugs for terminating the tenant feeder cables.
Why is an electronic trip unit preferred for this 400A metering application?
The solid-state electronic trip unit provides highly accurate, current-limiting protection that does not degrade over time or fluctuate with ambient temperature changes, ensuring reliable safety for commercial tenant mains.
