Description
Built for commercial and industrial facilities, the GE THLC436400 is a 400-amp, 3-pole current-limiting MCCB. It features fixed thermal-magnetic trip units for reliable long-time and instantaneous protection. The breaker mounts into GE switchboards, motor control centers, and individual enclosures. It accommodates dual 3/0 AWG to 250 kcmil or single 500 kcmil conductors. With a 200kAIC rating at 480V, it significantly reduces peak fault currents to safeguard sensitive downstream components.Specifications

Product FAQs
9 answersWhat frame size does the THLC436400 belong to?
The THLC436400 is part of the GE THLC4 frame, which accommodates current ratings from 250A to 400A.
Which lug kit is compatible with the THLC436400 circuit breaker?
The TCLK43 lug kit is used for both the line and load ends of THLC4 frame breakers. It accepts either one 3/0 AWG to 500 kcmil or two 3/0 AWG to 250 kcmil copper or aluminum wires.
How does the current-limiting feature of the THLC436400 benefit my electrical system?
As a current-limiting breaker, it restricts the peak let-through current and energy during a short circuit. This minimizes thermal and mechanical stress, protecting sensitive downstream components from severe fault damage.
What types of distribution equipment accept the THLC436400?
This breaker is designed to bolt directly into compatible GE switchboards, motor control centers, and individual enclosures.
Why might this breaker be labeled as ABB instead of General Electric?
ABB acquired GE Industrial Solutions in 2018. Depending on the production date, the THLC436400 may feature either ABB or GE branding. Both versions share the exact same form, fit, and function.
Can I use aluminum conductors with the standard lugs on the THLC436400?
Yes, the standard terminals are dual-rated for both copper (Cu) and aluminum (Al) conductors, supporting single or dual wire configurations per pole.
Are the thermal and magnetic trip settings adjustable on the THLC436400?
No, this breaker features a fixed thermal and fixed magnetic trip unit, providing preset long-time and instantaneous (LI) protection without field adjustability.
What is the difference between the THLC436400 and THLC436400WL?
The standard THLC436400 comes equipped with load lugs only. The THLC436400WL variant includes both line and load lugs factory-installed.
Which 12V DC shunt trip is compatible with the THLC436400?
The TFKSTA7R is a 12V DC shunt trip accessory compatible with the THLC4 frame, allowing for remote tripping capabilities.
