Product FAQs
8 answersWhat does the U43X suffix indicate on the HDL36150U43X?
The U43X suffix indicates that the breaker is equipped with a Micrologic 5.2 A (Ammeter) electronic solid-state trip unit. This provides adjustable Long-time, Short-time, and Instantaneous (LSI) overcurrent protection, along with an integrated ammeter display.
What trip functions are adjustable on the Micrologic 5.2 A trip unit?
The Micrologic 5.2 A trip unit provides LSI protection, allowing you to adjust the Long-time pickup and delay, Short-time pickup and delay, and Instantaneous pickup settings for precise selective coordination.
Does the HDL36150U43X use thermal-magnetic trip elements?
No, this breaker uses a solid-state electronic trip unit. Electronic trip units offer more precise and adjustable protection curves compared to traditional fixed thermal-magnetic breakers.
What type of mounting does the HDL36150U43X use?
This breaker features a feed-thru (unit mount) design, meaning it installs using mechanical lugs on both the line and load sides rather than plugging into a distribution bus.
Is this breaker compatible with Square D I-Line panelboards?
No, the HDL36150U43X is a unit-mount (feed-thru) breaker with lugs on both ends. It is not designed to plug into an I-Line bus. I-Line panelboards require a plug-in variant.
Can the HDL36150U43X be reverse fed?
Yes, this PowerPacT H-frame breaker is suitable for reverse-fed (back-fed) applications. The solid-state Micrologic trip unit does not restrict the breaker to forward-feeding only.
Does the HDL36150U43X include equipment ground fault protection?
No, this breaker features an LSI trip unit (Long-time, Short-time, Instantaneous). It does not include the Ground fault (G) protection function. If ground fault protection is required, a breaker with an LSIG trip unit is necessary.
Is the HDL36150U43X considered a Square D or Schneider Electric breaker?
Square D is a flagship brand of Schneider Electric. This PowerPacT H-frame breaker may be labeled under either the Square D or Schneider Electric brand name, but the physical product and HDL36150U43X catalog number are identical.
