Product FAQs
5 answersWhat does the WL suffix indicate in the THLC136100WL catalog number?
The WL suffix specifies that the breaker is supplied with factory-installed line and load lugs. Breakers ordered without this suffix typically require terminal lugs to be sourced and installed separately.
Is the THLC136100WL suitable for use in standard residential load centers?
No. This is a unit-mount, feed-thru molded case circuit breaker designed for commercial and industrial applications. It is specifically intended for installation in GE switchboards, motor control centers, and individual enclosures.
How does the current-limiting feature of the THLC1 frame operate during a fault?
As a current-limiting breaker, it is engineered to clear high-level short circuits in less than a half cycle. This rapid operation significantly reduces the peak let-through current and energy, protecting downstream electrical equipment from severe thermal and mechanical stress.
Are the trip settings on the THLC136100WL field-adjustable?
No. This breaker utilizes a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions are factory calibrated and cannot be modified by the installer.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions. Legacy GE molded case circuit breaker lines, including the THLC series, are now manufactured and distributed under the ABB brand portfolio while retaining their original GE catalog numbers to ensure direct replacement compatibility.
