ABB / General Electric THED136050WL Molded Case Circuit Breaker

In the GE E-150 frame nomenclature, the "WL" suffix indicates that the circuit breaker is shipped from the factory with line and load side lugs installed. These lugs are approved for terminating both copper and aluminum conductors.

Yes. GE THED series circuit breakers do not have internal line and load restrictions. They can be safely reverse fed if required by your specific panelboard or enclosure application.

Yes, this thermal-magnetic breaker is rated for DC applications up to 500VDC. It provides a 10kA interrupting capacity at both 250VDC and 500VDC, which is commonly required in heavy industrial and control panel setups.

ABB acquired GE Industrial Solutions in 2018. Because of this transition, newly manufactured THED136050WL breakers may feature ABB labels instead of the traditional General Electric logo. The physical dimensions, internal components, and performance ratings remain completely identical.

Torque specifications for the factory lugs vary based on the wire size used. Standard requirements are 35 in-lb for #10 AWG, 40 in-lb for #8 AWG, 45 in-lb for #6 to #4 AWG, and 50 in-lb for #3 AWG and larger. Always verify with the specifications printed directly on the breaker label before installation.
