ABB / General Electric TED134015 Molded Case Circuit Breaker

The TED134015 features a bolt-on mounting configuration specifically designed for General Electric A-Series and Spectra Series panelboards. It can also be installed in compatible GE motor control centers and switchboards that accept E150 line frames.

Yes. Since ABB acquired GE Industrial Solutions, the ABB Record Plus FBN36TE015RV is commonly used as a direct replacement for the TED134015. The ABB Tmax XT series also provides equivalent 15-amp, 3-pole options, though panelboard retrofits may require specific mounting hardware.

The GE TEF134015 shares the same E150 frame, dimensions, and bolt-on mounting style as the TED134015, making it physically interchangeable. However, it carries different fault current ratings. Ensure the replacement breaker meets or exceeds the short-circuit requirements of your specific application before installing.

The LI designation means this thermal-magnetic breaker provides Long-Time (L) and Instantaneous (I) fault protection. The Long-Time thermal element protects wiring from sustained overloads, while the Instantaneous magnetic coil trips immediately during short circuits. Both setpoints are factory-fixed on this model and cannot be adjusted in the field.

Yes, while commonly used for AC power distribution, this breaker is also rated for direct current systems up to 250VDC. It provides a 10kA interrupting capacity for DC applications. Electricians must ensure the system voltage and available fault current do not exceed these certified limits.

The TED134015 is generally equipped with TCAL12 load lugs. These extruded aluminum lugs are dual-rated for both copper and aluminum conductors. When terminating wires, ensure the conductor size matches the accepted gauge parameters and verify that all connections are secure.

To prevent high-resistance connections and thermal failure, lug screws must be tightened to the exact torque specification listed on the breaker's side label. A calibrated torque wrench or screwdriver is required by the National Electrical Code (NEC) to ensure proper clamping force on the conductors.

Yes, the GE E150 frame supports various internal and external modifications. Field-installable accessories for this line include auxiliary switches for status monitoring, shunt trips for remote disconnection, undervoltage releases, bell alarms, and locking devices for lockout/tagout procedures.
