Description
Operating within commercial power systems, the GE THED136125 is a 3-pole, 125A MCCB that provides essential overcurrent protection for 600VAC applications. This bolt-on breaker is engineered to install securely into GE A-Series and Spectra Series panelboards, as well as motor control centers. It serves as an ideal replacement for legacy TED136125 units. The breaker features a fixed thermal-magnetic trip mechanism with LI functions, delivering a 65kA interrupting rating at 240V.Specifications

Product FAQs
9 answersIs the ABB THED136125 the same as the GE THED136125?
Yes. Following ABB's acquisition of GE Industrial Solutions, this legacy E150 frame molded case circuit breaker may be branded as either ABB or General Electric depending on the production date. The physical footprint and technical specifications remain identical.
Can the THED136125 replace an older TED136125 breaker?
Yes. The THED136125 shares the exact same physical E150 frame dimensions as the standard TED136125 model, making it a direct bolt-on replacement. It offers a higher interrupting capacity (up to 65kAIC at 240V) than the standard-tier TED line.
Which panelboards are compatible with this breaker?
This bolt-on MCCB is engineered for direct installation into GE A-Series panelboards, GE Spectra Series panelboards, and standard Motor Control Centers (MCCs) configured for E-Frame breakers.
What does the E150 frame designation mean for this breaker?
The E150 frame size refers to GE's compact legacy MCCB footprint that supports circuit breakers rated up to 150 amps. This standard sizing ensures physical mounting interchangeability with other GE E-Frame units like the TEB, TEC, and TED series.
Can the THED136125 be reverse fed?
Yes. Breakers in the GE E150 frame series, including the THED line, are suitable for reverse feeding. This allows line and load connections to be inverted safely without compromising the thermal magnetic trip unit.
Does the THED136125 accept both copper and aluminum wiring?
Yes, the standard factory lugs are AL-CU rated. They accommodate 3 AWG to 3/0 AWG for copper conductors and 1 AWG to 3/0 AWG for aluminum conductors.
Can the THED136125 be used in DC power applications?
Yes. In addition to its AC voltage ratings, this breaker is rated for direct current systems, safely providing a 10kA interrupting capacity at both 250VDC and 500VDC.
What type of fault protection does the LI trip function provide?
The LI code designates Long-Time and Instantaneous tripping functions. The Long-Time delay protects the circuit against sustained electrical overloads, while the Instantaneous magnetic function clears high-current short circuits immediately.
Are the overcurrent trip settings on the THED136125 adjustable?
No. This breaker is equipped with a fixed thermal and fixed magnetic trip mechanism. The overload and short-circuit response thresholds are factory calibrated and cannot be modified in the field.
