Product FAQs

9 answers
What panelboards are compatible with the PGA36080U44A?

This breaker is designed specifically for installation in Square D I-Line panelboards and switchboards.

What does the U44A suffix mean on this Square D breaker?

The U44A designation indicates the breaker is equipped with a Micrologic 6.0A electronic trip unit. This provides an integrated ammeter and adjustable Long-Time, Short-Time, Instantaneous, and Ground-Fault (LSIG) protection.

What type of terminations are standard on the PGA36080U44A?

This breaker features an I-Line plug-on jaw connection on the line side and mechanical lugs on the load side.

What wire sizes do the load-side lugs accept?

The standard load lugs accommodate three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.

Is the PGA36080U44A rated for 100 percent continuous current?

No, this specific catalog number is standard-rated for 80 percent continuous current. Square D models rated for 100 percent continuous current typically include the letter C in the catalog number, such as PGA36080CU44A.

Does this breaker provide equipment ground-fault protection?

Yes, the included Micrologic 6.0A trip unit features adjustable ground-fault protection, allowing for precise coordination in systems requiring equipment ground-fault sensing.

Can the trip unit on the PGA36080U44A be swapped in the field?

Yes, PowerPacT P-Frame breakers equipped with Micrologic trip units allow for field interchangeability. The trip unit can be upgraded or replaced if system protection or monitoring requirements change.

How does the I-Line connection simplify installation?

The I-Line plug-on design allows the breaker to mount directly onto the panelboard bus with a jaw connection. This eliminates the need for line-side cabling and makes phase balancing much faster for panel builders.

How customizable is the protection on the Micrologic 6.0A trip unit?

The trip unit provides fully adjustable settings for Long-Time, Short-Time, Instantaneous, and Ground-Fault pickup and delay, allowing electricians to achieve precise coordination with other devices in the electrical system.
