Product FAQs
8 answersWhat panelboards are compatible with the THED126020 circuit breaker?
This breaker is designed for installation in GE A-Series panelboards, GE Spectra Series panelboards, and compatible motor control centers. It requires bolt-on mounting hardware specific to these enclosures.
What wire sizes and materials are approved for the THED126020 lugs?
The factory-installed lugs accept 14 to 3 AWG copper wire or 12 to 1 AWG aluminum wire. Ensure proper torque specifications are followed during installation to maintain a secure connection.
Can the THED126020 be used in DC applications?
Yes, this breaker is rated for DC systems up to 250VDC, providing an interrupting capacity of 20kA. This makes it suitable for specific industrial control and battery backup applications requiring a 2-pole configuration.
What is the interrupting capacity of this breaker at different AC voltages?
The THED126020 provides a maximum interrupting rating of 65kA at 240VAC, 25kA at 480VAC, and 18kA at 600VAC. Verify the available fault current at your installation point does not exceed these values.
Is the THED126020 part of the GE Spectra RMS or standard E-150 line?
The THED126020 belongs to the standard GE E-150 line of thermal-magnetic circuit breakers. It is not part of the Spectra RMS solid-state series, though it can be installed in Spectra Series panelboards.
Does the THED126020 offer adjustable trip settings?
No, this breaker features a fixed thermal-magnetic trip unit with long-time and instantaneous (LI) protection. If your application requires adjustable trip settings, you will need to select a breaker with an electronic trip unit.
Can the THED126020 be reverse fed?
Yes, GE E-150 line breakers, including the THED series, are suitable for reverse feed applications. Always verify your specific local electrical codes and panelboard labeling before reverse feeding a breaker.
Will the THED126020 fit in a standard Q-Line load center?
No, the THED126020 is an E-frame molded case circuit breaker designed for commercial and industrial panelboards. It is not compatible with standard residential Q-Line load centers that use THQL or THQP plug-on breakers.
