What does the C in the PGA36080CU31A catalog number indicate?

The C signifies that this circuit breaker is 100% rated. This allows the breaker to carry its full 800A continuous current rating without the standard 80% derating requirement.

What type of enclosures will accept the PGA36080CU31A circuit breaker?

This breaker features an I-Line style plug-in connection on the line side and is designed exclusively for installation in compatible Square D I-Line panelboards and switchboards. It cannot be used in standard unit-mount or drawout applications.

What specific protection functions does the Micrologic 3.0 trip unit provide?

The factory-installed Micrologic 3.0 electronic trip unit provides adjustable Long-Time (L) and Instantaneous (I) protection to safeguard against overloads and short circuits.

What wire sizes are accepted by the load-side lugs on this breaker?

The factory-installed load-side mechanical lugs accept three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.

How is the line-side connection made on the PGA36080CU31A?

The line side utilizes Square D I-Line plug-on jaws that snap directly onto the busbar stack in an I-Line panelboard. This allows for rapid installation and phase balancing without the need for bolted bus connections.

Does this PowerPacT P-frame breaker include a manual testing feature?

Yes, it includes an integral push-to-trip button on the front cover. This allows electricians to manually trip the breaker to verify the mechanical operation of the tripping mechanism during maintenance.

Can the trip unit on the PGA36080CU31A be replaced in the field?

Yes, PowerPacT P-frame circuit breakers feature interchangeable Micrologic trip units. The included Micrologic 3.0 trip unit can be removed and upgraded in the field if your application requires advanced metering or different protection functions.

What is the phase connection arrangement for this I-Line breaker?

This 3-pole breaker features a standard ABC phase connection for the I-Line busbar stack.

Does the PGA36080CU31A utilize true RMS sensing?

Yes, the Micrologic 3.0 electronic trip unit utilizes true RMS sensing to accurately measure current and provide reliable protection, even in electrical systems with harmonic distortion.
