Description
Built for demanding industrial applications, the GE THLC236150WL is a 150A current-limiting MCCB. By rapidly clearing faults, it provides superior protection for sensitive downstream equipment. This unit-mount breaker installs into GE switchboards and motor control centers, featuring factory-installed lugs for 4 AWG to 300 kcmil wiring. Rated for an exceptional 200 kAIC at 480VAC, the Q-Line THLC frame utilizes fixed thermal-magnetic trip technology for dependable LI protection.Specifications

Product FAQs
8 answersWhat type of equipment is the THLC236150WL designed to be installed in?
This THLC2 frame breaker is designed for use in GE Switchboards and Motor Control Centers.
What wire sizes are accepted by the terminals on this breaker?
The terminals accept wire gauges from 4 AWG up to 300 kcmil, and are rated for both copper (Cu) and aluminum (Al) conductors.
What does the WL suffix in the THLC236150WL catalog number mean?
The WL suffix indicates that the circuit breaker is supplied with factory-installed lugs for feed-thru wire connections.
How does the current limiting feature of this breaker protect my system?
Current limiting breakers like the THLC236150WL are designed to clear high-level short circuits extremely fast. This reduces the peak let-through energy, which helps protect downstream components from severe thermal and mechanical stress.
Can I adjust the trip curve on the THLC236150WL?
No. This breaker uses a thermal magnetic trip unit with fixed thermal and fixed magnetic settings for long-time and instantaneous (LI) protection.
Is the THLC236150WL manufactured by ABB or General Electric?
This breaker was originally designed by General Electric. Following the acquisition of GE Industrial Solutions by ABB, these THLC2 frame breakers are now produced and supported under the ABB brand.
What is the interrupting rating difference between 480V and 600V applications?
The breaker provides a high interrupting capacity of 200kAIC at both 240VAC and 480VAC. However, when applied at 600VAC, the maximum interrupting rating drops to 50kAIC.
How does this breaker mount inside the enclosure?
The THLC236150WL is a unit mount breaker, meaning it bolts directly to the mounting pan or chassis rather than plugging onto a busbar.
