Description
Part of GE's Q-Line family, the THLC134100 is a 3-pole, 100A molded case circuit breaker designed for commercial and industrial environments. It delivers reliable thermal-magnetic protection for heavy-duty electrical systems. This bolt-on MCCB mounts securely into compatible GE A-Series panelboards, switchboards, and motor control centers. It is replaced by the modern ABB XT Series for new installations. Engineered to restrict let-through energy, it provides a 200kAIC rating at 480V.Specifications

Product FAQs
7 answersWhich panelboards and enclosures are compatible with the THLC134100?
This breaker is designed for installation in GE A-Series panelboards, switchboards, and motor control centers.
What wire sizes and materials are accepted by the lugs on this breaker?
The factory terminal lugs accept 3 AWG to 3/0 AWG copper wire, or 1 AWG to 3/0 AWG aluminum wire.
How does the THLC134100 mount into a panelboard?
This is a bolt-on circuit breaker. It secures directly to the panelboard bus using bolted connections, providing a robust and secure electrical contact suitable for industrial applications.
What does the current limiting designation mean for the THLC134100?
As a current limiting breaker, it clears high-magnitude faults in under a half cycle. This rapid clearing time significantly reduces peak let-through current and let-through energy, protecting downstream equipment from severe thermal and magnetic stress.
Does the THLC134100 require external fuses to achieve its 200kAIC rating?
No, this breaker is fully rated to interrupt up to 200kA at both 240V and 480V AC on its own, without the need for upstream current limiting fuses.
Are the thermal and magnetic trip settings adjustable on this breaker?
No, the THLC134100 features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection without adjustable dials.
Is the THLC134100 manufactured by ABB or General Electric?
ABB acquired the GE Industrial Solutions division. Depending on the production date, this breaker may carry either the GE or ABB brand label. Both versions are identical in form, fit, and function.
