ABB / General Electric TED134020 Molded Case Circuit Breaker

Yes, General Electric TED series circuit breakers are rated for reverse feeding [1.4.4]. This allows you to connect the incoming line power to either the top or bottom terminals without affecting the internal thermal-magnetic trip calibration.

Yes, this 20-amp breaker is HACR rated. It is certified to protect Heating, Air Conditioning, and Refrigeration equipment, safely handling the starting surges associated with multi-motor compressor loads.

No, this is an E-Frame commercial molded case circuit breaker with a heavy-duty bolt-on configuration. It will not fit in standard residential Powermark Gold load centers, which require miniature THQL or THQB breakers. It is specifically designed for commercial A-Series and Spectra panelboards.

The LI code stands for Long-Time and Instantaneous protection. The fixed thermal element provides Long-Time (L) protection against gradual overloads, while the fixed magnetic element provides Instantaneous (I) protection, immediately tripping the breaker if a severe short circuit occurs.

Yes, it is UL listed for High-Intensity Discharge (HID) lighting systems. This means the breaker contacts and internal mechanisms are designed to withstand the high initial inrush currents of HID ballasts without experiencing nuisance tripping.

When the breaker detects a fault and trips, the handle will snap to a neutral middle position between ON and OFF. To restore power, first push the handle fully to the OFF position to reset the internal mechanism, and then firmly push it back to the ON position.

Since ABB acquired GE Industrial Solutions, the legacy E-150 frame TED series has been phased out. For new standalone panel builds, ABB Tmax XT1 or XT2 series breakers are the modern equivalents. However, if you are replacing a breaker in an existing GE A-Series or Spectra panel, you must use a TED frame to match the existing bolt-on bus hardware.

Yes, the factory lugs are rated for both copper and aluminum conductors. When using aluminum wire, the terminals accept 12 AWG to 2 AWG sizes. Always ensure the wire is properly stripped and an appropriate anti-oxidant compound is applied before torquing the lug.
