Description
Operating at 600A, this 3-pole molded case circuit breaker protects heavy industrial power networks, providing LI protection on 600VAC circuits. This LG-frame breaker is built to mount into Eaton Series G panelboards and switchboards. As an older generation component, it has been replaced by the newer Power Defense PDG33K0600TFAJ. Featuring a 50 kAIC rating at 480V, it uses a fixed thermal and adjustable magnetic trip mechanism. The unit is 80% rated, HACR certified, and includes lugs.Specifications

Product FAQs
7 answersWhat does the "FAG" suffix mean in the LGS3600FAG catalog number?
In Eaton's Series G nomenclature, "FAG" indicates the breaker is a complete unit equipped with a fixed thermal and adjustable magnetic trip unit (FA), and it includes standard factory-installed line and load lugs (G).
What wire sizes do the standard lugs on the LGS3600FAG accept?
The factory-installed line and load lugs on this LG-frame breaker accommodate two conductors per phase, accepting 2/0 AWG to 500 kcmil aluminum or copper wire. Ensure proper torque specifications are followed during installation as outlined on the breaker label.
How does the LI trip unit function on this 600A breaker?
The LI (Long-Time and Instantaneous) designation means this breaker provides fixed thermal overload protection permanently set at 600 amps. However, the magnetic short-circuit protection is adjustable, allowing electricians to fine-tune the instantaneous trip threshold to coordinate with other devices in the system.
What equipment is the LGS3600FAG compatible with?
This LG-frame molded case circuit breaker is designed for installation in Eaton Series G panelboards, switchboards, and motor control centers (MCCs). It utilizes a standard feed-thru unit mount design.
Is the LGS3600FAG rated for 100 percent continuous operation?
No, this is a standard-rated breaker. Per National Electrical Code (NEC) requirements for standard thermal-magnetic breakers, it should be loaded to a maximum of 80 percent of its 600A continuous rating (480 amps) when installed in an enclosure.
Is the LGS3600FAG HACR rated for HVAC applications?
Yes, Eaton LG-frame circuit breakers are HACR rated, making this unit suitable for use with heating, air conditioning, and refrigeration equipment that requires this specific certification.
How is the adjustable magnetic trip set on the LGS3600FAG?
The instantaneous magnetic trip is adjusted using the dials located on the front face of the trip unit. This must be configured by a qualified electrician during installation to ensure proper short-circuit coordination based on the specific fault current calculations of the facility.
