Product FAQs
8 answersWhich panelboards and enclosures are compatible with the THEF136030?
This E-Frame breaker is designed for bolt-on installation in GE A-Series panelboards, GE switchboards, and compatible motor control centers.
What wire sizes are accepted by the standard lugs on this breaker?
The included lugs accept 14 to 3 AWG copper (Cu) conductors or 12 to 1 AWG aluminum (Al) conductors. Ensure proper torque specifications are followed during installation.
Are the trip settings on the THEF136030 adjustable?
No, this breaker features a fixed thermal and fixed magnetic trip unit. It provides standard Long-Time and Instantaneous (LI) protection without adjustable dials.
Can the THEF136030 be utilized in direct current (DC) systems?
Yes, this breaker is rated for use in DC applications up to 250VDC, providing an interrupting capacity of 10kAIC at that voltage.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions. Legacy GE molded case circuit breakers, including the THEF E-Frame series, are now manufactured and supported under the ABB brand portfolio.
What is the modern replacement for the legacy THEF136030?
The THEF136030 is a legacy E-Frame model that is commonly superseded by the THED136030 for modern upgrades and replacements.
How is the THEF136030 secured within the panelboard?
It utilizes a bolt-on connection type. The breaker bolts directly to the panelboard bus, providing a secure, vibration resistant connection typical in commercial and industrial environments.
What does the H in the THEF frame designation signify?
In GE nomenclature, the H indicates a high interrupting capacity version of the E-Frame breaker. The THEF136030 handles up to 65kAIC at 240VAC and 25kAIC at 480VAC, which provides enhanced fault protection compared to standard TEF models.
