ABB / General Electric TED134150WL Molded Case Circuit Breaker

The WL suffix designates that the breaker is supplied from the factory with mechanical lugs installed on both the line and load sides, rather than being provided as a bare-terminal breaker for busbar mounting.

ABB acquired General Electric Industrial Solutions. As a result, legacy GE E-frame breakers like the TED series may be shipped with either GE or ABB branding on the front label depending on the manufacturing date, but they are physically and electrically identical.

Breaking higher DC voltages requires more arc-extinguishing capability. To achieve the 500VDC rating, you must wire multiple poles in series according to the manufacturer guidelines. Single-pole interruption at 500VDC will exceed the interrupting capacity of the breaker.

Standard GE TED series thermal-magnetic circuit breakers do not have Line and Load restrictions printed on the faceplate, meaning they are typically suitable for reverse feeding applications. Always verify local code requirements before reverse feeding.

No. This specific breaker features fixed thermal and fixed magnetic trip elements. It does not offer field-adjustable dials for long-time delay, short-time pickup, or instantaneous override functions.

Yes. Because this breaker carries straight voltage ratings (480VAC and 600VAC) rather than a slash rating (like 480Y/277VAC), it is fully rated for phase-to-phase faults on ungrounded, resistance-grounded, or corner-grounded delta systems up to its maximum rated voltage.

No. The LI (Long-Time, Instantaneous) designation means it only provides standard thermal overload and magnetic short-circuit protection. It does not include integral ground fault (LSIG) or earth leakage trip functions.
