Description
Designed for maximum safety, the GE THLC136040WL is a 3-pole, 40A molded case circuit breaker. This Q-Line device features a fixed thermal-magnetic trip mechanism. Engineered for unit-mount applications, it fits into GE switchboards, motor control centers, and individual enclosures. The included lugs accept 14-3 AWG copper wiring. As a current-limiting breaker with a 200 kAIC rating at 480VAC, it rapidly clears faults to minimize let-through energy, protecting downstream circuits.Specifications

Product FAQs
8 answersWhat does the "WL" suffix in the THLC136040WL catalog number indicate?
In GE nomenclature, the "WL" suffix indicates that the circuit breaker is supplied with factory-installed copper/aluminum (Cu/Al) line and load lugs.
What enclosures and panels are compatible with the THLC136040WL?
This unit-mount, feed-thru breaker is designed for installation in GE switchboards, motor control centers, and individual enclosures that accept THLC1 frame molded case circuit breakers.
Can the trip settings on the THLC136040WL be adjusted in the field?
No, this breaker features a fixed thermal and fixed magnetic (LI) trip unit. The long-time and instantaneous trip functions are factory-set and cannot be modified.
What is the advantage of using a current-limiting breaker like the THLC136040WL?
Current-limiting breakers are designed to clear electrical faults extremely fast, significantly reducing the let-through energy and peak current. This provides enhanced protection for downstream circuits and equipment against severe short circuits.
How does the interrupting rating of the THLC136040WL scale with system voltage?
While it offers a high interrupting capacity of 200kAIC at 240VAC and 480VAC, the rating decreases to 50kAIC when applied to 600VAC systems. Electricians must verify the available fault current at the specific installation voltage.
Are line and load lugs included with the THLC136040WL, and what wire types do they accept?
Yes, the breaker includes factory-installed line and load lugs. They are rated for both copper (14 to 3 AWG) and aluminum (12 to 1 AWG) conductors.
Can I install the THLC136040WL in a standard residential load center?
No, this is a THLC1 frame molded case circuit breaker designed for commercial and industrial switchboards, motor control centers, and specific enclosures. It will not fit in standard residential load centers.
What internal accessories are compatible with the THLC136040WL?
The THLC1 frame shares the same internal accessories as GE Type TED circuit breakers. This includes auxiliary switches, shunt trips, and undervoltage releases designed for the TED family.
