Product FAQs
8 answersWhat type of enclosures or panels accept the LLP36600U31X circuit breaker?
This unit mount circuit breaker is designed for installation in Square D switchboards, motor control centers, and individual commercial enclosures that accommodate PowerPacT L-frame breakers.
What adjustments are available on the Micrologic 3.3 trip unit included with this breaker?
The U31X designation indicates a Micrologic 3.3 electronic trip unit. It provides adjustable long-time and instantaneous (LI) trip functions, allowing precise coordination for overload and short circuit protection.
What size conductors can be terminated on the lugs of the LLP36600U31X?
The factory installed lugs accept two 2/0 AWG to 500 kcmil aluminum or copper conductors per phase.
Is this breaker suitable for systems with high fault current availability?
Yes, the L interrupting class provides a high interrupting rating of 100 kAIC at 480VAC and 50 kAIC at 600VAC, making it suitable for industrial systems with substantial available fault current.
How does the LLP36600U31X differ from the LGP36600U31X or LJP36600U31X?
The LLP model features an L interrupting class rated at 100 kAIC at 480VAC. The LGP and LJP models share the same physical frame and trip unit but have lower interrupting ratings of 35 kAIC and 65 kAIC at 480VAC, respectively.
Does this breaker plug into an I-Line panelboard?
No, the LLP36600U31X is a unit mount, bolt-on circuit breaker. For I-Line panelboard installations, an LLA or LJA prefix breaker with I-Line jaw connections is required.
Does the LLP36600U31X provide ground fault protection?
No, the Micrologic 3.3 trip unit only provides long-time and instantaneous (LI) protection. If equipment ground fault protection is required, a breaker with a Micrologic 6.3 (LSIG) trip unit is necessary.
Can this 3-pole breaker be used on a single-phase system?
Yes, PowerPacT L-frame breakers with Micrologic trip units can be applied on single-phase systems, but they are restricted to 240VAC maximum and require wiring through any two poles.
