You're right, information on "THQE" breakers is incredibly scarce. You've done your research and found the key point: the resemblance to and potential evolution of the THQL/TQL lineage.Here's a breakdown of my thoughts and potential approach based on the information available and your description

Why THQE is Likely Just a Variant/Older Labeling:
Scarcity of Information

The overwhelming lack of information about THQE strongly suggests it's not a current or common designation. If it were a widely used or significantly different breaker type, there would be readily available specs, cross-references, and troubleshooting guides.

Similarity to THQL/TQL

The "THQ" prefix strongly links it to the GE family of breakers that include the THQL and its predecessor, the TQL. GE often used similar naming conventions for breakers in the same product line with minor variations or improvements.

Age of the Breaker

You described the breaker as "crusty old." This indicates it's likely from a period when labeling conventions might have been less standardized or more prone to change over time.

The "E" Suffix

The suffix in electrical component designations can mean a variety of things, but often represents a revision level, a minor feature change, or a manufacturing plant code. In this case, it may simply be an older GE code.

Why THQC is the Best Bet for Replacement



2-Pole 60A Match

You correctly identified that the amperage (60A) and number of poles (2) are crucial. The THQC2160 is a 2-pole 60A breaker.

Direct Replacement Claims

Your statement that "a direct replacement of a new breaker is the THQC series" is significant. If you have that information from a reliable source (e.g., a distributor, electrician forum, or GE documentation), it's the strongest evidence available.

THQC's Intended Application

THQC breakers are typically used in residential and light commercial applications, which aligns with the likely use of a 2-pole 60A breaker.

Physical Compatibility

Visually compare the existing THQE breaker's dimensions, mounting points, and busbar connections to the THQC2160. Ideally, obtain a THQC2160 and physically compare it to the old breaker before installing it.

Recommended Approach


Confirm THQC2160 Compatibility



Physical Inspection

This is crucial. The THQC2160 needs to physically fit into the panel slot previously occupied by the THQE. Check the depth, width, and how it clips or screws into the busbar. Pay very close attention to the bus connection.



Panel Compatibility

Make sure the existing panel is rated to accept THQC series breakers. If the panel is very old, it might be designed for only older breaker types. This is less likely if it previously used a THQ-style breaker. Look for any markings on the panel indicating compatible breaker series.2.

Consult with an Electrical Professional (Highly Recommended)

While you've done your research, a licensed electrician can assess the existing panel, wiring, and overall electrical system to ensure the THQC2160 is a safe and appropriate replacement. They can also verify the panel's maximum breaker ratings. They can use their expertise to confirm the THQE's original purpose within the circuit and ensure the THQC provides the same protection.3.

Document Everything

Take detailed photos of the existing THQE breaker, the panel, and the wiring. Keep records of your research and any conversations you have with distributors or electricians.

Important Safety Notes



Electricity is dangerous. If you are not a qualified electrician, do not attempt to replace the breaker yourself. Improper installation can lead to electrical shock, fire, or damage to equipment.

Turn off the main breaker that feeds the panel before removing the old breaker or installing the new one. Confirm that the circuit is de-energized with a voltage tester.

Properly torque all connections when installing the new breaker. Loose connections can cause overheating and electrical fires.

Test the breaker after installation to ensure it trips correctly under overload conditions (but do so safely and in accordance with applicable codes).In conclusion, based on the information you've provided and the lack of readily available data on the THQE, the THQC2160 appears to be the most likely replacement. However, physical compatibility must be verified, and consulting with a qualified electrician is strongly* recommended to ensure safety and proper operation.
