Description
Part of the Q-Line family, the GE THLC234200 is a 3-pole, 200A current-limiting molded case circuit breaker designed for heavy-duty commercial and industrial applications. It installs into GE switchboards and motor control centers using a standard bolt-on connection. Featuring a thermal-magnetic trip unit with long-time and instantaneous functions, this breaker delivers exceptional fault protection with a massive 200kAIC rating at both 240V and 480V to safely isolate downstream equipment.Specifications

Product FAQs
7 answersWhat type of enclosures or panels accept the THLC234200 breaker?
This bolt-on circuit breaker is specifically designed for installation in General Electric switchboards and motor control centers. It is not intended for standard residential load centers.
How does the current-limiting feature of the THLC234200 benefit an electrical system?
Current-limiting breakers clear short circuits in a fraction of a cycle. This rapid response significantly reduces the peak let-through current and thermal energy, providing enhanced protection for sensitive downstream components and wiring.
What are the conductor size limits for the factory lugs on this 200A breaker?
The included lugs accommodate wire sizes ranging from 4 AWG up to 300 kcmil. They are dual-rated for use with either copper or aluminum conductors.
Can the thermal-magnetic trip settings on the THLC234200 be adjusted in the field?
No, this model features a fixed thermal-magnetic trip unit. The long-time and instantaneous trip functions are factory-calibrated and cannot be modified by the user.
What does the 200kAIC rating indicate for industrial applications?
An interrupting capacity of 200kAIC means the breaker can safely clear a fault current of up to 200,000 amps at 480VAC. This high rating is critical for industrial facilities with large transformers where available fault currents exceed standard breaker limits.
Is the THLC234200 suitable for 240V applications?
Yes. Although it has a maximum voltage rating of 480VAC, it is fully compatible with 240VAC systems. It provides the same 200kAIC maximum interrupting capacity at both voltage levels.
What frame size does the THLC234200 belong to?
This breaker is built on the GE THLC2 frame. When replacing an existing unit, ensuring the frame type matches is essential for proper fitment and busbar alignment in your switchboard or motor control center.
