Product FAQs
9 answersWhat panelboards are compatible with the THED124040?
The THED124040 is designed for use in GE A-Series and Spectra Series panelboards. It mounts directly to the bus using a bolt-on connection.
What are the acceptable wire sizes and materials for the THED124040 terminals?
The factory-installed lugs accommodate 14 to 3 AWG copper conductors or 12 to 1 AWG aluminum conductors. Ensure proper torque specifications are followed during installation.
Can the THED124040 replace an older TED124040 breaker?
Yes, the THED124040 serves as a direct, higher-rated replacement for the older TED124040 model. It shares the exact same E-frame footprint and bolt-on mounting but offers a higher interrupting capacity.
Why is this breaker listed as both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, this E-frame breaker may be branded as either ABB or GE, but the physical dimensions, fit, and technical specifications remain identical.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the thermal-magnetic trip unit provides both Long-Time (L) and Instantaneous (I) protection. The long-time function protects against sustained overloads, while the instantaneous function trips the breaker immediately during a short circuit.
Is the THED124040 suitable for reverse feeding?
Yes, this breaker is rated for reverse feed applications. This allows it to be back-fed in a panelboard, which is often required when used as a main breaker or in specific generator and solar setups.
Is this breaker HACR rated?
Yes, the THED124040 is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific designation for safe operation.
Can this breaker be used in DC applications?
Yes, in addition to its standard AC ratings, this breaker is rated for up to 250VDC with a 10kA interrupting capacity, making it suitable for specific industrial DC control panels.
What frame size is the THED124040?
This breaker is part of the GE E-150 Line and utilizes the TED frame, which is a compact molded case design commonly used in commercial and industrial distribution.
