Product FAQs
7 answersCan I interchange the trip unit on this breaker?
No. The PGL36120 is equipped with the Basic Electronic ET 1.0I trip unit. Unlike the standard MicroLogic trip units available for some PowerPacT P-frame models, the ET 1.0I is fixed and cannot be interchanged in the field.
What are the physical dimensions of this breaker?
The PowerPacT P-frame breaker measures 16.16 inches high, 8.05 inches wide, and 8.27 inches deep.
Can this unit-mount breaker be installed in an I-Line panelboard?
No. The PGL36120 is designed with a feed-thru connection for direct installation in switchboards, motor control centers, and individual enclosures. It does not include the plug-on jaws required for I-Line bus mounting.
Are there alternative lug kits available to accommodate larger wire sizes?
Yes. While the standard lugs accept up to four 500 kcmil conductors per phase, you can swap them for optional mechanical lug kits like the AL1200P7KU. This specific kit accommodates up to 750 kcmil wire to meet different installation requirements.
Does this breaker support field-installable internal accessories?
Yes. Most internal accessories, such as auxiliary switches and shunt trips, are standardized across the PowerPacT P-frame series. This allows panel builders to easily modify the breaker during panel assembly.
What does the G in the part number signify?
The G denotes the specific interrupting capacity tier within the PowerPacT P-frame family. For this model, the G-tier delivers a maximum interrupting rating of 65kA at 240VAC and 35kA at 480VAC.
How does the ET 1.0I trip unit protect the electrical system?
The integrated ET 1.0I solid-state electronic trip unit provides long-time protection to handle persistent overloads and instantaneous protection to quickly clear severe short circuits.
