ABB / General Electric TED124040 Molded Case Circuit Breaker

This E frame breaker is designed to bolt directly into GE A-Series and Spectra Series panelboards. It is also commonly used in GE motor control centers and switchboards that accept E150 line breakers.

The WL suffix indicates that the breaker is factory packaged with both line and load lugs. The standard TED124040 typically includes load lugs only, though both share the exact same physical dimensions and electrical specifications.

Yes. If your system requires a higher fault current rating, the THED124040 is the high interrupting version of this exact E150 frame. It provides 25kA at 480VAC compared to the 18kA rating of the standard TED model.

Yes, this breaker supports reverse feed configurations. The non-interchangeable thermal magnetic trip unit operates safely regardless of whether power is supplied to the top or bottom terminals.

Yes, the TED124040 is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment that requires this specific protection standard.

It utilizes TCAL12 load lugs, which 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.

ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, the TED124040 may feature either GE or ABB branding. Both versions are identical in form, fit, and function, and are fully interchangeable.
